New battery electric vehicles premature

The appearance of a new electric bicycle, the key parts - the quality of the laptop battery itself, there may be “fatal” flaws. Yesterday, a few years the electric car technology research and sales experience into a red-hi engineers, revealed to reporters as well as many supermarket stores to sell electric car electric car batteries it is not configured in accordance with the principle of battery maintenance, resulting in a large number of new significantly reduce battery life.

Bought a lot of electric vehicles, will have such a feeling, bought the car not long, but somehow can not help feeling that power is insufficient, in the maintenance of points, after-sales service staff will be informed, “to replace the battery dying.” According to the Consumer Association’s complaints Nanjing analysis showed that, with the electric vehicle market continues to develop, followed by complaints on the quality of electric cars are the rapid growth of cases, among which, 8 as is for the poor quality of electric vehicle hp batteries reflected.

Electric bicycle battery bad Why is it that easy? Hi in red under the guidance of engineers, journalists at the East came to a point-of-sale electric bicycle, a good plan in accordance with the prior discussion, the reporter disguised as a fancy electric vehicles, require sales staff will unload the car battery, the journalists face a special request, the sales staff seemed a bit reluctant. Into work quietly told reporters that the first note of the date of the battery production, the reporter saw a battery box mounted on the three batteries, the date of its production was not the same, which is 2 August 16, 2004 production , and the other one is September 6 production. Hi red to the sales staff was asked from time to time they have to charge the battery, in the face of the problem appears to face each other at a loss.

“The battery electric vehicles to hide the fact on here, and some sellers are not professional knowledge, it should be can not shirk its responsibility”! Cheng Hung Hei told reporters that the main battery electric vehicles is the stereotype, and by in-house, composed of sulfuric acid solution, if a certain period of time not to charge the battery, then the solution will precipitate sulfate, then have a resistance, would result in battery power directly decline. Specific performance will not be long for the charging, the battery will be hot, when cycling mileage will be manifested as inadequate. Into workers explained that the dealers in terms of electric vehicles for their own electric cars should be sold at least once a month and a half in charge, or will directly affect the life of electric vehicle batteries, in accordance with an electric car can be recharged more than 200 calculation , if we do not charge for more than two months, the battery life may be reduced by half. Buy a car but in reality, very few people have asked open the battery cover to see inside the battery manufacture date. Work into the public is advised to buy electric car, we must require sales staff will be equipped with a battery to open the lid, carefully check the date of built-in battery production, and most secure way is to choose the date of the battery factory one and a half months in the .

Hydrogenation few points into the development of fuel cell vehicles in Japan barriers

Recently, the Japanese experts estimate that by 2010, the fuel cell market size is about 1 trillion yen (110 yen about 1 U.S. dollars) by 2020 is expected to reach ¥ 8,000,000,000,000. However, the development of fuel cells are also encountered some difficulties. For example, the price is too expensive, too few hydrogen refueling station. Metropolitan area in Japan is currently only 10 hydrogen refueling station. Although the rate of a hydrogen can be driven 350 km, but because too few hydrogen refueling station, the battery in the left two-thirds of the hydrogen, they often have to start thinking about where the next hydrogenation.

Japan in May this year issued a formal “strategy to create new industries”, the development and application of fuel cells on the pivotal position. December 2002, Toyota and Honda to market fuel cell vehicle, the two car companies to the Japanese government to pay 55 fuel cell vehicles. Now, the two companies have already produced fuel cell vehicle 28.

Where the fuel cell vehicle by the person that spoke with one voice to praise the performance of vehicles. The noise is very small, a maximum of up to 145 kilometers per hour, a hydrogen fuel supplement may be traveling 350 kilometers, and refueling vehicles traveling a similar distance. According to experts estimate that by 2020, Japan’s fuel cell vehicle up to five million.

At the same time, fuel cells are entering the homes of ordinary people. In May this year, Tokyo Gas Company to demonstrate the use of residential fuel cell demonstration.

A new generation of lithium-ion battery Lithium & Nickel Synthesis

A new generation of lithium-ion battery Lithium & Nickel Synthesis

Recently, an important compound with independent intellectual property rights of synthesis of metal oxide materials have been in Beijing successfully applied to industrial production process, a new generation of key-ion rechargeable laptop battery is Lithium nickel plate material officially put into production. The leading-edge technology at home and abroad is 4 years ago returning from overseas, led by its researchers Dr. Lu Following the rationale and manganese cobalt acid lithium then made an important achievement. At present, the production line of lithium nickel production capacity of 500 tons / year.

It is understood that the synthesis of lithium nickel production is internationally recognized as problems, only laboratory samples at home and abroad, there is no industrial production and application, which the establishment of production lines fills Lithium nickel international large-scale production of the blank, so that Lithium nickel practical applications become a reality. Nickel is a multi-valence metal elements, affecting the synthesis of lithium nickel factors is very complicated. Synthesis conditions of the process of change toshiba battery, it is easy to generate a slight impurities, reducing the storage capacity of materials. In the charge-discharge cycle, because of the existence of impurities in materials often lead to the collapse of crystal structure, and there will be serious impact on the electrochemical cycle life and safety. CITIC solid profits UNITA new Materials Technology Research Institute and Beijing University New Energy Materials and Technology Laboratory through 3 years of research, in a large number of laboratory work based on the synthesis of a unique and integrated a number of key technologies, developed the rationale for the production of acid in the nickel key equipment to realize the size of lithium nickel production industry.

Li-ion secondary battery as a high-power, short in the past 10 years, to replace the traditional nickel-cadmium and nickel-metal hydride secondary battery, has become the mobile phones, notebook computers, camcorders, DVD, CD and MD small mobile electronic products such as the main application of power, to promote the development of electronic and communication industry has played an important role. But so far in ion battery cathode material is mainly used in lithium cobalt. Lithium cobalt has a higher capacity and longer service life, although the comparison has been widely used, but the Cobalt is a strategic resource, a large scale in China have not found the value of cobalt mining, drilling of resources into the basic dependence Japan, which is very expensive, and nickel acid lithium in the process of charging and discharging poor thermal stability limit in a wide range of lithium-ion batteries in the field of application.

With the electric motor to power batteries and power storage batteries represented by large-ion rechargeable battery Kam rapid development of the plate material resources are being and safety of a higher demand, the traditional cathode materials for lithium nickel is obviously difficult to meet the lithium-ion battery development, it is necessary to seek a new generation of high-energy plasma to sleep cathode material. Preparation of soil by Bo and his staff will research into the current of the Ni-acid, lithium has an excellent electrochemical performance, capacity than lead-acid high health material more than 20%. The experimental results show that, as the treatment of chemical elements have been doped lithium nickel crystal structure in the stability of charge-discharge state, so that the material produced by the lithium battery recycling is not only superior performance, security, good performance, but also has a good filling ratio discharge performance. In addition, the synthetic material as a result of spherical particles, narrow particle size distribution, tap density, specific surface area of small, suitable for the production of various types of hammer-ion rechargeable battery.

The face of the earth’s resources has proven reserves of nickel is more than ten times the number of diamond and silver elements on the toxicity of the natural environment is also far less than the cobalt element, therefore, whether it is from the abundance of resources, goods, lead-acid or keys, to address the future resources, energy and environmental issues of great significance. China has rich resources of nickel, in this based on the development of a new generation of silver-ion batteries are Lithium nickel plate material is particularly relevant. Lithium nickel production line set up for full use of China’s nickel resources, China’s lithium-ion battery cathode material moving away from total reliance on imported raw materials situation, so that we can accelerate the development of their own intellectual property rights, high-performance lithium-ion toshiba satellite m100 battery, toshiba satellite m105 battery, lithium-ion battery to broaden the range of applications, led China’s energy-related industrial development will have a significant and far-reaching impact.

Doctor Lu by researchers and the development of lithium nickel establishment of production lines, indicating that China’s lithium-ion battery cathode materials have been in the international leading level, China has entered the field of energy materials in the ranks of developed countries.

Chlorophyll battery

Recently, there have been news reports that American scientists in the extraction of spinach chlorophyll-protein, the use of their characteristics of light energy conversion, solar cells made of the chlorophyll. Scientists said that after further improvement, this battery promising clean production, energy supply for the Pocket PC.

This chlorophyll is a kind of battery life based on solar cells, and its working principle is the conversion of light energy into electrical energy. This new invention will make use of their high performance and low-cost access to commercial production for the Pocket PC to provide a clean and green energy.

Scientists from a variety of spinach photosynthesis in isolated proteins, and Add them between two layers of conductive material. When there is light reach the micro-devices, the current rise. These proteins from spinach leaves in light to help plants into chlorophyll.

However, extraction of these proteins is not an easy task. These protein molecules are very fragile, and when they are removed from the natural environment, the work often can not continue. So the scientists put them in a mixture called peptide surfactant molecules. Such protection molecules in these proteins have the energy to form a protective membrane around so that they feel the same as in plants.

Protein was placed in a book on thin sheet metal, attached to a layer of conductive metal, the top of the organic material is conductive. When the light irradiation in the “fake sandwich” when will the release of proteins electronics, spread a layer of the metal layer under the current form.

Of course, the toshiba satellite m110 battery, toshiba satellite m115 battery also needs to be improved. Now, they only have 21 days to sustain the current, and then on the end-of-life, so must try to extend the current time they have; now they are absorbed into the energy conversion efficiency of only 12%. Scientists hope that this proportion could rise to 20%, then the efficiency of its market than the silicon solar cell is even higher.

Bottleneck in computer & notebook batteries

Bottleneck in computer & notebook batteries

With the progress of the notebook battery computer technology, From a mobile office concept has already become a reality. In order to meet the needs of mobile and mainstream manufacturers are introducing more powerful, more stable system of ultra-thin notebooks. Used for this ultra-thin battery, but because of the lack of electricity has become a new bottleneck in mobile office. And, in addition to persistent power, the battery is very expensive prices, and a piece of notebook batteries accounted for 10% of the overall price -15%, then an ultra-thin laptop battery should have the characteristics of what it mobile office to meet the demand? From the practical point of view we may wish to analyze the design of laptop battery standard.

Industry experts believe that time is of the battery. Ultra-thin notebook computers because of the thin body makes room for the installation of the toshiba battery becomes more limited, and the battery means to reduce the volume of the power supply even shorter time, not every ultra-thin notebook computers can be up to standard the battery life. At present, a common ultra-thin notebook battery time between 2-3 hours, a good brand can be achieved for about four hours, there are higher, such as NECS820 will be able to provide electricity five hours time, and if equipped with backup battery, the life of up to 11.8 hours. Moreover, the computer which is designed to extend the battery very thin flat-shaped, and its size and the fuselage in line with the expansion of the bottom of the chassis battery integrated with the fuselage, and fully maintained the smooth state of the fuselage.

However, even the best batteries, its power can not be unlimited, and the total time spent, and a charge can be completed in the shortest possible time that the battery may be the user’s mobile office to offer as much convenience and efficiency. Which most users are often easy to forget where the most ordinary laptop charging time is 3-7 hours, with better products to be completed in 2.4 hours recharge.

In addition, some regular users to minimize the use of a variety of components to achieve extended battery life of purpose, for example, do not use CD-ROM, hard disk read as little as possible to reduce the screen brightness or simply dormant and so on. These approaches can indeed maintain the battery a little more time, but “a temporary solution”, select the design of a battery with excellent products, in order to fully enjoy the convenience of mobile office with the fun.

Special equipment sub-industry growth opportunity

“Development of China’s electronic special equipment for the electronics and information industry laptop battery to provide strong support,” This is the consensus of the industry. However, China’s electronic special equipment manufacturing industry is still very small scale, can not meet domestic demand.

According to statistics, in 2003 China’s electronic special equipment sales revenue was 34.2 billion yuan, accounting for only the electronic information product manufacturing sector by 0.2%, while international electronic equipment in the electronic information industry, the proportion of about 5% ~ 10%. Domestic electronics enterprises grasp of China’s electronic information industry brought about by the rapid development of the opportunity, to extend the product line, expand equipment services, has become the focus of widespread concern.

Semiconductor Equipment extend to other areas of toshiba battery

According to market research firm statistics, in 2003 the semiconductor equipment market in China reached 1.7 billion U.S. dollars, accounting for global market sales of 5.2%. More to industry estimates, the next 10 years, China’s semiconductor and IC equipment market will be more than 20 billion U.S. dollars. However, the rapid development of China’s semiconductor and integrated circuit industries as compared to domestic semiconductor equipment manufacturing industry is relatively slow development of the new 6-inch, 8-inch IC factories are almost all imported equipment from abroad, whether in technical or in the capital are constraining the development of China’s IC industry. To this end, the industry’s authoritative source, the semiconductor integrated circuit device companies in China should go step-by-step: by the year 2010, our part of the mainstream production line to achieve the commercialization of key equipment; through external cooperation, will have the advantage of a small amount of the industrialization of the products; actively develop FPD , MEMS, batteries and other electronic equipment production lines based on products used in semiconductor devices. This is for the domestic semiconductor equipment business provides a broad market.

At the same time, industry experts said that by 2020, following the next-generation 45-nanometer lithography machines will be there. Half of the next generation lithography technology is new, even if engaged in the original production lithography machine is the new foreign companies, therefore, when the domestic enterprises and foreign companies almost on the same starting line, the difference is not great. The 18 nanometer technology in 2018 will be launched in the domestic equipment companies do have a chance.

In addition, the semiconductor devices in a wide range of applications in other fields, as well as domestic equipment manufacturers opportunities. According to the Ministry of Information Industry Electronic Information Products Management Division Wang Bo China, the foundation of electronic products to small and micro-oriented development, semiconductor device has been increasingly applied to the LED (including semiconductor lighting), TFT-LCD, PDP, MEMS , VFD, in areas such as solar cells.

Figures show that the global LED next 5 years for 20% annual growth rate from 2004 to 3200 million U.S. dollars in 2008 increased to 5.6 billion U.S. dollars, while China’s LED market grew 30%, LPE / VPE / MOCVD, and many other semiconductor devices will be useless. Although there is a nurturing process of the market, but the lighting project at the country’s support, should have good prospects.

2003 global LCD TV sales reached 35.7 billion U.S. dollars, will reach 47 billion U.S. dollars this year, the next 4 years an area of 10 inches and larger LCD panels to expand production capacity of 4 times, the output will be 9.6 million this year to grow to 2008 3980 10,000, almost all production equipment of semiconductor devices; the global OLED market in 2003 was 263 million U.S. dollars, by 2008 will grow to 3.4 billion U.S. dollars, including equipment used in lithography, etching machines, absorbed significant equipment; MEMS industry average annual growth rate of more than 20%, in 2003 the global production value of more than 9 billion U.S. dollars, the need for lithography equipment mainly machines, etching machines, binding equipment. Domestic equipment manufacturers can develop new markets in these areas.

In addition, MOVCD, PECVD and other equipment should also be used in the battery industry well in 2003, CRE Qixing battery production equipment in short supply in this area describes the business of domestic equipment is worth to try.

SMT equipment starting from the lead-free

In 2003, the rapid development of electronic information industry, led by the application of China’s SMT has been further enhanced, the total imports of Taiwan SMT 7648, total imports amounted to 1.091 billion U.S. dollars, showing China’s market demand for STM large equipment.

Wuhan Fiberhome Systems Technology Co., Ltd. Xian Fei SMT engineers told reporters in the field of SMT, the current domestic enterprises in the software can also be hardware from foreign companies is also very different in terms of a change in the short term it is very difficult, but from domestic enterprises simple broken small SMT devices, such as reflow, printers and so on.

Electronic equipment in China Gold Association, the Secretary-General told reporters Cunzhong that lead-free SMT toshiba tecra a7 battery, toshiba tecra s2 battery equipment is the equipment companies are facing a new opportunity, domestic enterprises must seize this opportunity and of great importance to lead-free research and development equipment.

Wang Bo-hua said that on the surface mount device, the lead with a two-tier significance: one is that the equipment itself does not lead-free components and processing technology, and the second is used to adapt to the user’s request for lead-free production lines the use of surface mount equipment. From the printing equipment, reflow equipment, wave soldering equipment to a variety of optical inspection equipment, from the use of lead solder to lead-free solder used, due to the different chemical composition, for the equipment industry will inevitably bring new challenges, in terms of software or from the hardware side, the equipment will add a new degree of difficulty. At present, Shenzhen and Shenzhen Jin East Billiton has already made considerable achievements. Other equipment for the domestic enterprises to enter the basis in the field.

Chip manufacturing equipment components concern

With the electronic machine to short, small, light, thin direction gradually speeding up the pace of development and China’s mobile phone, PC, DVD and other electronic products for the growing market, driven components of chip demand. It is understood that in 2002 global production of chip components 1 trillion next year will reach 1.5 trillion by 2010 will reach 2.5 trillion. Figures indicate that the “Eleventh Five-Year” period, the world needs at least 150 chip components production lines, nearly 150 million investment in equipment.

According to experts, at present, the production of components of our equipment, but the production of chip components is not more than business. In future, the traditional components of the amount will be less and less, on-chip components will be increasing demand, this is an opportunity for business equipment. In addition, the automotive electronics industry as a result of the rapid development of sensor devices should also be a hot business equipment.

The basic unit will be assembled hundreds of them would constitute a battery pack, battery pack and then together to form a power station. Can be flexible depending on the needs of different size to the assembly of fuel cell power plant. The basic unit of fuel cell design standards can carry out large-scale pre-production, so the fuel cell power plant construction and low cost, short construction cycle. In addition, as a result of fuel-cell light weight, small size, high specific power, relatively easy to move up, so it is particularly suitable in remote areas or islands to build power stations, or build a distributed power plant.

Fuel diversity. Although the fuel cell hydrogen is mainly the work of the material, but it can be used for fuel gas, methanol, liquefied petroleum gas and other hydrocarbons. According to the actual situation, in line with local conditions to use a different fuel, or combination of different fuel use, can reach local materials, to save resources.

Pollution-free. The main product of fuel cells is water, essentially non-emission of harmful gases, it is a very clean source of energy. It is reported that a number of fuel cell emissions of harmful gases in the United States national standards for environmental protection by two orders of magnitude lower. In addition, the fuel cell is a stationary power generation, has no mechanical transmission device, only in the control system and other auxiliary devices have moving parts, thus it is the work of a small vibration, low noise.

Due to high cost of fuel cell, generating cost-effective as other methods do not, we can not get the promotion. Therefore, only the cost of significantly reduced and further enhance the service life, fuel cells will enhance their competitiveness. According to the U.S. departments of statistics, when the construction cost of 3 U.S. dollars per watt hours (1994 has reached), the fuel cell will be able to enter the market; when reduced to about 2 U.S. dollars, can be in remote areas as an independent power generating system; When reduced to about one U.S. dollars, the market will expand rapidly. 1 U.S. dollars to achieve this goal, it is necessary to the life of fuel cells will be increased to 40,000 hours.

The development of fuel cells is now very fast speed. In accordance with national plans, by 2000, Japan’s fuel cell power output will be close to 2200 megawatts, the United States will reach 500 megawatts in 2000, Europe will reach 500 ~ 900 MW. By 2010, the world’s total installed capacity of fuel cells will reach 60,000 MW. As a new type of fuel cell energy, is still relatively high cost, long life is not enough, power is still relatively small. However, with the depth of the research work, these problems will be solved. Many scientists believe that the era of knowledge economy in the 21st century, fuel cells will account for in the field of energy in a pivotal position, therefore, have the fourth-generation power technologies, research and development of fuel cells with the significance of the next century.

Dianchi Lake every year 100,000 tons of refuse what way


Dianchi Lake salvage garbage placed where it? Dianchi Lake every day along the flow of garbage to deal with the future, what will? This reporter visited the HKMA Kunming Yunnan, Kunming Environmental Protection Bureau, Kunming sanitation experts monitoring center after that, a massive clean-up campaign refuse Dianchi Lake basin has been fully launched in the next few days, but the inflow of garbage along the Dianchi Lake how to deal with, it is worth exploring one of the new problems.

Refuse disposal sites will be built lake

Kunming, Yunnan Province, according to the HKMA person in charge, the current agricultural non-point source pollution of Dianchi Lake pollution accounts for 40 percent, and 15 lake township agricultural population of about 700,000 people, an annual output of 100,000 tons solid waste per day about 280 tons. Collected as a result of the lack of lake township removal treatment systems, the main river into the lake and piles of refuse, garbage dumping in rural areas has become the main channel, garbage and sewage directly or indirectly discharged into Dianchi Lake.

To strengthen the management of garbage lake, early this month, the Government of Kunming Dianchi Lake basin has seven districts and counties, as well as municipal government departments to sign “comprehensive management of the target Dianchi responsibility”, 7 District Government and the township (street offices) signed responsibility and the responsibility to establish the risk of mortgage system objectives pc764 battery, tc030 battery. 19, Chenggong County, first of all towns and districts have made the preparation of the 60 Board responsible to pay 120,000 gold Dianchi management responsibility to set an example, caused great shock in the county. Lake of the four districts and counties clear 15 township counties (districts) long and township (town) responsible for long as the first in 15 villages and towns to manage the establishment of Dianchi Lake, Lake area is responsible for the maintenance of cleaning the river, rural solid waste the work of removal and disposal of objects. Can not be completed on the responsibility of evaluation indicators, and will not be paid bonuses year-end appraisal, the risk of mortgage payment will also be turned over to the financial.

Followed by the district government, will be 15 in the lake township (street offices) to build agricultural solid waste disposal site 5, each village to build a refuse collection point 1-3 months to build about 700, with 32 removal trucks. These efforts will be completed this year, 1 / 3, complete next year.

Kunming landfill operation overload

Kunming Kunming sanitation and Environmental Protection Monitoring Center of the persons concerned that the current waste disposal area in Kunming City, particularly in the technology and cost, there are some insurmountable difficulties.

It is understood that the landfill, incineration power generation, high-temperature composting is now usually three kinds of waste, but all have their pros and cons of each approach. Landfill garbage is more of the principal means of its shortcomings is an area landfill, and the use of a short time (generally 10 years), high cost, especially in the treatment of landfill leachate has become a from all walks of life he could do nothing but pay close attention to the problem; and waste incineration power generation, it is characterized by a significant volume reduction through incineration to reduce the volume of garbage to make half or more, but the drawback is that the recoverable resources burned, releasing toxic gas, such as dioxins, mercury batteries, such as steam, and produce toxic and hazardous slag and dust; and high-temperature composting of organic need people to separate garbage and other refuse, and some analysts pointed out that it is actually relatively low efficiency, by sale and use of constraints inconvenience.

Monitoring Center, according to a sanitation engineer, the Kunming area currently two things landfill construction scale a total of more than 500, with a total investment of nearly 200 million, was designed daily capacity of 1500 tons, while the actual is overloaded, two each day, “eat,” 2300 tons solid waste, both in May 2001 into the use of the landfill site, originally expected useful life of 6 years to 3 years now time, has removed most of the space.

Dianchi who refuse disposal “bill”

For many years engaged in a senior engineer of environmental engineering calculations to press accounts, in theory, to deal with a ton of garbage to take up to 30 plurality, but far from fees and funding can not meet this requirement.

Landfill in the eastern suburbs as an example, 1300 tons of refuse daily, one-year deal with the cost of nearly 1,500 million, together with the financial allocations and charges may only reach over 200 million, making the landfill Kunming “stretched.” It is reported that the current waste disposal charges in Kunming still uses the old standard, government organizations and institutions to collect 60 per tonne, 20 Enterprise, residents 5 yuan per day, but the actual collection rate is very low, and the gap are in need of financial subsidies .

The Engineering pointed out that generally, to build a large landfill plant will take 1-2 billion, to build a large-scale take more than 20 million, and then told reporters he has a case in point: In May last year, hubbub of the units to be 3 to the joint venture was to invest 40 million U.S. dollars, to establish the first waste incineration power plant, but because of various reasons the project more than 1 year did not seem to have happened since, ibm battery, and 08k8192 battery. According to the senior engineers estimated that out of proportion to the input and the actual recovery may be one of the reasons why the project move forward.

Caohai Dianchi Lake Basin to watch women’s collections a year to 10 tons of garbage, the senior engineers are very worried about: “management of pollution in Dianchi Lake were his own, everyone must ask yourself what to do?”

The new lithium-ion rechargeable battery cathode materials

The new lithium-ion rechargeable battery cathode materials

Sanyo Electric recently successful trial using a new generation of lithium-ion rechargeable laptop battery cathode materials for the candidate - LiFePO4 battery, and in “the 45th Battery Symposium” published the contents of the security.

The characteristics of LiFePO is: LiCoO2 cathode materials with the existing compared to lower-cost materials and high temperature will not release oxygen, thus the high security. In addition to Sanyo Electric, the seminar on the five research institutions have published the relevant results of basic research has been in full swing. For example, the University of Tokyo Institute of Technology announced the fast charge characteristics of LiFePO4. However, most of these studies remain in the pilot phase electrode, the battery can be used for the actual evaluation of the electrode characteristics has not yet begun. Sanyo Electric and the trial of a diameter of 18mm, high 65mm cylindrical toshiba batteries, and battery on the security characteristics of the test. The use of a graphite anode.

Safety test in the detection of the trial cylindrical barbed nail cells and the circumstances Overcharge. Spurs to nail after 30 seconds the temperature rose to about +110 ℃, but then did not continue to rise, but slowly falling down. Charge during the test, as a result of charging excessive electrolyte decomposition temperature up to +120 ℃, while playing an open valve immediately after the power was cut off. From the above results, obtained in the security issues and there is no significant conclusions. Battery characteristics to 0.25A for discharge, the discharge capacity of 1095mAh, the energy density per unit volume for 214Wh / l, the energy density of unit weight for 96.5Wh / kg.

Issues currently faced by the characteristics of low temperature low. +60 ℃ at 96mAh, +25 ℃, when a discharge capacity of 888mAh to 0 ℃ will dramatically reduce the 375mAh. At the meeting, someone asked directly: “LiFePO4 there so many problems, there will be attractive to you? Have hoped to put in actual use it?.” In this regard, speakers from a personal point of view, said: “In addition to previously noted that the problem of low electronic conductivity, this time found a low-temperature characteristics of the problem of low, I personally feel that the future emergence of new issues.”

Canon to launch small-scale fuel cells for hydrogen supply device

Canon developed the use of MEMS technology to create the hydrogen supply device, and in November 29, 2004 ~ 30, held in Kyoto “PowerMEMS 2004″ were released on. Applications for digital cameras and other portable devices on the fuel cell.

The role of hydrogen gas supply device is to preserve high-pressure storage tank of hydrogen needed to release the amount of an atmospheric pressure dropped after the supply to the fuel cell. Its structure and the use of divers to breathe oxygen devices like the valve is very common (Canon). MEMS technology will be adopted to reduce the size 8mm × 8mm × 1mm.

The use of hydrogen gas supply device to the 300μm thick silicon films plus 3 stacked structure. With hydrogen pumps connected to the bottom with a single-chip switch, the resulting hydrogen gas to enter through the middle layer of the channel to form a single-chip into the top single-chip, single-chip from the top of the hole supply to the fuel cell. First single-chip top-level processing toshiba satellite m40 battery, toshiba satellite m45 battery, with the middle layer to the stacked-on-chip processing, the final class with the most single-chip stack processing.

The lower silicon chip switch installed into the diameter of hydrogen 250μm. Through the opening and closing the switch to adjust the hydrogen supply. Released when it is published only in the use of nitrogen can be the result of normal work, it was used to test the hydrogen has been the same result.

Micro-generator can replace cell phone batteries

Georgia Institute of Technology announced that with the Massachusetts Institute of Technology, working closely with scientists, they have successfully developed a micro-generators, only 10 mm in diameter, is the continuing use of mobile phone battery is more than 10 times. Scientists will be held in January next year, the International Conference on Micro Electro Mechanical System published the results of this gratifying.

Georgia Institute of Technology is one of 10 open construction, computer, engineering, management and other professional, a total of 16,000 students in the United States is to train African-American women scientists and the best scientists, a university, research university is 2003-2004 academic year a total of 342 million U.S. dollars of research funding.

Over the years, more and more compact electronic products, and its battery has a larger volume of plays. In order to solve this problem, the scientists have been dedicated to the development of micro-generators, and put forward a number of different principles of micro-generators. And the Georgia Institute of Technology scientists have developed such a generator to replace the phone battery, indicating that micro-generators to enter the electronic products to replace conventional batteries and an important step.

The principle of the micro-generator is installed in a chip on the induction coil, so that a small rotating magnet around the coil, resulting in sufficient current. Through continuous testing, the rotating speed of the magnet is now up to 100,000 per minute lap, the speed can generate 1.1 kilowatts of electricity, enough to replace the phone toshiba satellite m50 battery, toshiba satellite m55 battery. The researchers said that will be sure to have a speed of 20-50 kilowatts of power for laptop computers. In order to improve the rotation speed, the most critical problem is how to avoid rotating magnet in the process of fracture. Centrifugal force generated by high-speed rotating magnets broken enough to make, in order to solve this problem, researchers continue to improve the size of magnet and wrapped in titanium alloys in.

Bottlenecks in digital music player

Bottlenecks in digital music player



United States May 25 local time (GMT May 26) messages, digital music players is becoming a necessity in people's lives, but its battery life is really worrying. The newest player capable of storing thousands of songs, almost all of the individuals included in the collection. But even as the most popular Apple iPod and other players, several best-selling models, the life of its rechargeable battery(hp nc6120 battery, hp nc6140 battery, hp nc6200 battery) can only be sustained for about 1 year.



Player has already spent hundreds of dollars of users, often had no choice but to update the battery and 100 U.S. dollars to spend a lot of grievances. Whether in the cocktail party or networking forums are full of fans of the digital player and its many vendors complain. These indeed have been some dissatisfaction with the settlement. Such as Apple Computer since starting in November 2003 launched a 99 U.S. dollars to update the iPod battery services.



Music lovers are expensive if you want to avoid spending money, will have to take a long time to sacrifice size or features such as broadcast to achieve the objectives. NPD's market research department manager of industry analysis Ross - Rubin said: "The size of the smaller players, the same performance in other circumstances, its battery life, the more difficult it is to maintain."



popular iPod player, one of the reasons is that its product is only equal to the largest size of a deck of cards, weighs only 5.6 ounces (about 157 grams). However, the application of such a small player in the sustainable use of the battery can only be 8 hours. By contrast, Dell quite another memory, weighs 7.6 ounces player sustainable use of the battery is 20 hours, equivalent to twice the former.



Repeatedly charging the battery will shorten battery life. Other factors, including the player's LCD screen the same size and type of impact on battery life. The length of playback time format also depends on the battery. Windows Media Player files smaller than that of other popular MP3 format, the less power consumption.



Another solution to the issue of battery replacement is purchased using the flash player, flash-based players than the iPod hard drive several hundred dollars cheaper, using a one-time battery.



Or can also use the so-called better quality battery, according to market research firm NPD said Rubin, iRiver and Dell's use of the lithium polymer battery than the iPod's lithium-ion batteries are much better. Rubin said: "The lithium-polymer battery is probably the best you can find the battery. This is the first use of the iPod battery(gd761, kd476, td347)."



IRiver said that if the daily average of four hours to play, IRiver rechargeable battery can last 4-5 years. IPod's battery can only use two.



Another option is to buy the replacement of the rechargeable battery, such as California, "Milpitas laboratory to create" the battery. The company said its hard disk drives used in the rechargeable battery player sells for 49 U.S. dollars, you can continue to use 14 hours and can be easily replaced by the user himself.



56 million to develop hydrogen fuel cell



In the Evening News under the auspices of the enthusiastic, Chen Qing crown elderly "women's apartment to be the word of" the invention of the patent is finally have the place. Yesterday, the private enterprises in Changsha Electric Group Fung and Chen on the old patent cooperation agreement signed, the group will spend 56 million yuan, and to develop the old Chen, "Hydrogen fuel cells" project.



The past few days, this newspaper reported that the consecutive home crowds of making the old Chen, who arrange to receive a daily basis the development of matters relating to patent as many as dozens of passengers, Chen was once the old cold-shouldered by the people of the patent has become sought after it. Through our "matchmaking", Changsha Electric Group Fung, chairman of Japan Mr Lai, finally, in good faith, and technical strength touched Chen old, from a number of "pro-mention" those who win. After several days of talks and demonstration yesterday Mr Lai Chen personally drove to the old factory received its visit, the two sides signed a patent cooperation agreement. Under the agreement, HSBC will be put on the early development of the Group of 500,000 yuan of funds, the two sides in the cooperation within 3 months to create 3 5000-watt, "hydrogen fuel cell," a prototype for the end of December this year passed before the technical evaluation. Next year, the HSBC Group(hp nc6220 battery, hp nc6230 battery, hp nx6110 battery) will come up with projects on a total investment of 56 million yuan, the realization of large-scale production.



Yesterday, Chen told reporters old also revealed a "secret": "Hydrogen fuel cells" project maturity, it will take the lead in application to electric vehicles, energy, the time before 2008 to produce China's first "people can afford" of electric vehicles. Mr Lai said that when the first line of electric vehicles will be donated to the evening, to express his appreciation.

Fuel cell bus of China

xFuel cell bus of China



Today, "China's fuel cell bus demonstration project," signed a vehicle procurement contract, procurement of Science and Technology from the United States three Chrysler hydrogen fuel cell bus. As a developing country, China became the first fuel cell bus began running the country. Next year, people in Beijing will be able to take on such a vehicle.



The project is two years, several foreign companies through competitive bidding, and ultimately the Chinese chose to Maesalong grams, three cars to order at more than 10 million yuan next year will be put into use in Beijing, and will provide services for the Beijing Olympic Games(sony vgp-bps2:vgp-bps2, vgp-bps2a, vgp-bpl2).



Stone will be the Secretary-General Ministry of Science and Technology, Central: The Chinese developed and this car will also run three experiments abroad, for comparison, and abroad they have compared to the eve of entering the industry, but I believe that such activities will accelerate the development of Chinese enterprises pace, there will be future development of Chinese enterprises in China-fuel vehicles on roads.



Japan's all-ceramic fuel cell development



Power companies by the various large-scale joint operation of the Central Power Research Institute in Japan has been committed to developing the full use of the heat-resistant ceramic fuel cells, at present, this work has yet known. The researchers do not use metal parts, but only the use of ceramic parts to connect power, which succeeded in raising the heat resistance. In the power generation efficiency is very high temperature of 1000 degrees Celsius to work, each square centimeter of electrolyte to achieve the output power of 1 W, which is equivalent to the traditional fuel cell 5 times. Expected that this technology will be applied to the family and the fuel cell vehicle. Institute for the mobilization of the battery manufacturers and machinery manufacturers to carry out joint research. Ceramics made by the fuel cell is the first in the world(dell latitude d600 battery, dell latitude d610 battery), the Institute hopes to realize 5 years later that the practical use of fuel cells.



Development there is the prospect of a solution is called "solid oxide-type" of the fuel cell. Fuel cell power generation in general is in part as a "cell" to get the reaction of oxygen with hydrogen to generate electricity. Electrode and electrolyte membrane placed overlap, and then connect the use of metal materials to connect a number of cell, and then collect the power cell, thereby enhancing the overall output power. Connect with the use of materials has always been easy processing and easy to pass current nickel plate. However, as the metal will be oxidized at a high temperature and aging, and therefore the need for power generation electrolyzer degrees in temperature control, so that the expense of output power. On the other hand, even if the connection between the ceramic, as a result of a chemical reaction caused by aging, people have worried that the hydrogen as fuel may leak.



Central Research Institute of Electric Power in order to inhibit chemical changes, add a calcium inorganic oxides, dissolves in aqueous solution into a sludge, and then in the electrode surface to form a thickness of 10 micron uniform ceramic membrane, thereby generating parts connected together.



If at the same time the use of ceramics and metals, such as different types of materials, as a result of heat expansion rate at different, that there are cracks, and the new technology to solve the long-term issue. Durability is also improved in the 1000 degrees C operating temperature under continuous operation time of 2,000 hours(372772-001, pb994a, hp nc6110 battery), equivalent to the original fuel cell 50 times. Now, the endurance test is still in progress, in order to achieve practical, the researchers hope to work longer hours to 10,000 hours.

Fake mobile phone batteries insider profits

Fake mobile phone batteries insider profits

(Trackback: .)http://www.discount-laptop-batteries.co.uk/today/2009/06/10/fake-mobile-phone-batteries-insider-profits/

I am sure the fake Nokia batteries exploded wounding also heard a great deal of news, and now many of my friends for the Nokia battery also had a fear, after all, is to carry mobile phones, and involved in their own security issues. So what is fake battery; with What's the difference between original equipment batteries; how to identify these issues of concern to everyone.

Insider profits fake batteries, low raw material costs

The cost of counterfeit goods very low battery, each battery costs only 2.5 yuan, the primary wholesale market price is 4 dollars a general in the market retail price of about 50-70 yuan, but also some black businessmen as original battery to sales, is doubling its profits. Why detract from the fact that a mobile phone battery costs only 2.5 yuan, which we may think that sounds unlikely, after all, as we often use a one-time battery not so cheap, not to mention is that these can be recharged many times you use the cell phone battery, but There have been able to have such a low price with good reason. As we all know, used batteries are used in special chemical waste, the general can not be used as to deal with garbage. Relevant state departments will be in order to avoid special handling of environmental pollution.

In developed countries, the law of chemical waste disposal requirements are particularly stringent. Thus many countries these chemicals will be shipped to foreign countries refuse to deal with, and this is a waste. Unfortunately, we have a lot of people devoted to domestic acquisition of such waste. It is said that these fake battery(dell latitude c610 battery, dell latitude c640 battery, dell latitude c800 battery) is from Fuzhou, the raw materials, such as battery recycling point to come back to buy bulk, the cost is extremely low prices are calculated in tons.

The same low labor costs, mobile phone batteries "production plant", the production of simple tools, simple table

These underground factories generally start with these places to buy back used batteries bulk, and then dismantling them simple useful carbon batteries, aluminum shell and other parts and then assembled into the battery, and its production process is quite simple, it requires only a few workers and the CLP iron like a small tool. One can imagine that the cost of these batteries is almost negligible.

The production process of mobile phone batteries

These are some black-market mobile phone batteries mobile phone accessories factory workshop or individual points from the volume of waste battery recycling used batteries to buy back, and then the demolition of their own by hand, extraction of available materials such as batteries welded together, and then fitted with the battery outside of the plastic Shell and the relevant labels on it. The entire production process is quite simple, very low production costs, the equipment required for simple devices such as electric iron only, and its size is usually only a few workers can be productive.

The regular battery manufacturers have to go through the relevant departments of national production of special permit to enter the industry, but also the quality of enterprises, raw material sources, such as recycling of waste products, there are stringent regulations. General small business can not have the ability to enter the energy industry, let alone the individual.

Phone batteries up to 100 times profits

We have said in front of its low production cost, is basically the cost of each cell at 2.5 yuan. Ex-factory price of 4 yuan. And to the retail market, the distributor further camouflage and deception, such as the original battery to battery sales. Price up to 2XX yuan, flexor calculation, the profit reached 100 times! Really amazing.

On the counter in such cells is very often false

JS in general before, this battery is also a very good camouflage, sell 70-80 million is not a problem. Profits have been up about 30 times.

Losses caused by counterfeit batteries

First of all, that is certainly economic losses. To spend 70-80 million to buy a camouflage battery, looks like the cheaper than the original, but in fact the performance of such batteries and thus fail to nominal value. Lack of standby time, fever. Conditions are common and so on. And most of this cell death itself may be the most used batteries(dell latitude c810 battery, dell latitude c840 battery, dell latitude cpi battery), so life will not be long. 3 months to almost useless. Therefore, JS is also very striking to tell you that the battery warranty for 3 months. To the user caused great economic losses.

The second is the security issue. Because there is no manufacturing done in accordance with the standard, and there is no security measure quality. Mobile phone batteries that can easily produce some security issues. Easily made when the charge of excessive heat, causing fire, such as the phenomenon of spontaneous combustion. Another is likely to charge at any time when violence charge, in order to not be able to use later. Become a real waste batteries. And chemical pollution of the environment into a piece of garbage. Impact on human health.

Can be said that the fake batteries are detrimental rather than beneficial. We should consciously resist the purchase. But do not that the market for all non-original batteries are unsafe with poor performance. In fact, the market still has a lot of professional battery manufacturer, their products are trustworthy. GPass common, Desai, TCL and so on such products, it is still worth buying public.

Remember not to buy the so-called compatible battery business, or the so-called A cargo, B goods with original equipment batteries. These are likely to be false. Only buy the regular products manufacturers can be quality assurance, is also more secure to use. If you had the battery charge when the battery broken or bursting battery charge of this situation, the general who is to buy fake or non-brand battery cells, on the contrary there is little original battery in such a situation.

Focus on recycling of waste batteries

Focus on recycling of waste batteries



All along, the primary and secondary schools in Shenyang and college students from the environmental point of view of the recycling of waste batteries( dell inspiron 8100 battery, dell inspiron 8200 battery, dell latitude c500 battery). It is understood, Shenyang Normal University, Shenyang Medical College, Liaoning University and other colleges and universities up recycling of waste batteries have nearly as many festivals. For this reason, many schools in the city asked the Environmental Protection Agency, these batteries exactly how to deal with. May 24, from Shenyang Environmental Protection Bureau was informed that: nearly Festival battery recycling is actually a "superfluous" is no longer current environmental protection department encourages the units or individuals focused on the recycling of waste batteries.



From the "encouraged" to "not encourage"



Shenyang Environmental Protection Bureau, according to Solid Waste Management Department Deputy DirectorXu Yunchuandescription: Shenyang used batteries for recycling, there had been two very different attitudes have, that is, from three or four years ago "to encourage the recovery of" to today's "not to encourage recycling," and the attitude of these two are from the environmental point of view. In recent years, the abolition of the environmental impact of batteries has become a hot topic of environmental protection of the batteries on the environment and human health hazards in the community was caused by a larger response.



Batteries containing mercury and mercury volatilization temperature low, is a large heavy metal toxicity. But even the high-mercury batteries, and its low mercury content. Battery with a hard shell and the protective effect of the dilution of a large number of spam and consumer groups dispersed, making batteries will not cause too much pollution. However, the economic interests of individuals in order to concentrate a lot of waste battery recycling, hastily ripping case, to recover valuable parts, not to discard the residue so that it may lead to mercury pollution in some areas.



Last year, the State has promulgated "battery waste pollution prevention and control technology policy", which clearly must be sent to specialized waste battery disposal centers focused on the disposal of all kinds is prohibited on the collection of the incineration of waste batteries. At the same time, units or individuals are no longer encouraged to focus on recycling of waste batteries.



IntroductionXu Yunchuan, Shenyang City, the management of waste batteries from the original means "end of management" upgrade "the source of adjustment." After "the source of adjustment", the battery manufacturers will produce "green batteries" and "environmentally-friendly battery", that is, low-mercury, mercury-free batteries, so as to ensure that the environment from abuse.



Focus on waste batteries



At present, many schools in Shenyang City, the campus has a battery recycling box, students are also very conscious of waste batteries in the box. The starting point to do so is to reduce the hazards of waste batteries and re-use.



For those who have been collecting waste batteries(dell latitude d505 battery, dell latitude d510 battery, dell latitude d520 battery), said the environmental protection department should be sent to specialized centers focused on the disposal of the disposal. No unit or individual is prohibited on the collection of a variety of incineration of waste batteries. Shenyang is currently used batteries can be transported to two s, one located in Shenyang City, Metro sub-district of Shenyang Industrial Solid Waste Disposal Center, and the other is located outside the city of Anshan in Liaoning Province batteries disposal center. Have been collected waste batteries by units and individuals in Shenyang Environmental Protection Bureau will be sent to the two batteries for professional disposal.



Radical Battery Pollution



In order to fundamentally radical battery pollution in Shenyang will be the battery manufacturers and battery market consolidation will be the amount of mercury do not meet national standards of battery out of the market. For manufacturers, it should be gradually reduced and eventually the production of the battery no longer use mercury batteries at the same time minimizing the risk of possible pollution caused by harmful elements, reducing the production of waste batteries, from the source reduction and control of pollution.



In addition, producers should gradually increase the proportion of alkaline manganese batteries, the phasing out of battery paste to develop lithium-ion batteries and Ni-MH battery rechargeable batteries, such as production, and ultimately to replace nickel-cadmium batteries.



Tibet has become a total installed capacity of photovoltaic cells in China's largest provinces, autonomous regions



Solar Energy Research Institute has recently learned from the autonomous region, Tibet has implemented with the "Tibet Project Sunshine," "the light of scientific plans," "Ali photoelectric plan" to implement the special and greatly ease tensions in Tibet the situation of conventional energy sources.



It is learned that Tibet has built a small independent photovoltaic power station at the county level 14, which has become China's photovoltaic power plants, the largest total installed capacity of photovoltaic cells of the provinces, autonomous regions, including the Nima Nagqu County, photovoltaic power station, the multi - County photovoltaic power plants installed photovoltaic cells to achieve a total capacity of 80 kilowatts, respectively, 120 kW, effectively improve the local herdsmen's electricity shortage; in communications, microwave communications relay stations 700 kilowatts of photovoltaic power has been more than 1,300 small-scale photovoltaic power plants, and photovoltaic system to provide power to the power of communication is my area of major development trends; in radio and television industries(dell latitude c510 battery, dell latitude c540 battery, dell latitude c600 battery), Ali Shiquanhe, Gerze door with disabilities such as mine have been completed more than 20 Block poor solar-powered television turntable, there are about more than 400 solar-powered satellite television system; photovoltaic power in the household, the region has been to promote the application of photovoltaic power appliances around 7 million units around.

Hydrogen fuel cell

Hydrogen fuel cell

One of the elderly over sixty, in order to reduce cell damage to the environment, take the lead in Weifang made the concept of leasing the battery(75uyf, 1691p, dell inspiron 2500 battery), and started to invest in the creation of their own the cause of the battery lease.



The old man named Zhao new fields, is in Weifang, a retired Bureau cadres, 63-year-old this year. His early e-learning technology, in 1964 and graduated from Shandong University, in the subsequent decades, has been engaged in electronic-related industries, the use of batteries and their characteristics very well. The end of last year, Zhao field that a new lease on the battery information, the decision to do something for the environmental protection of its power, and therefore carried out in the city to explore leasing the battery.



After the idea, in March this year, Tian Zhao pension from their own money out of more than 4000 yuan, pre-purchased a part of battery charging equipment and rechargeable batteries, and began to try to engage in leasing the battery industry. Tian Zhao told reporters that he had been contacted and Weifang College, and the first pilot in the hospital, if the trials are successful, their business will further expand the battery lease.



He also told reporters that big a button battery(dell inspiron 3700 battery, dell inspiron 3800 battery, dell inspiron 4000 battery) to 600,000 liters of water pollution, and a rechargeable battery after ordinary "use - charge - to use" can be repeatedly used 500 times, both to save energy and protect the environment, and their consultation with the manufacturers, the last can not be used in rechargeable batteries returned to manufacturers, so that once the battery leasing business in the whole society will greatly improve the daily cell damage to the environment.

How to distinguish genuine Motorola V680 Battery

User recently received, saying that the Motorola V680 battery more fake, so fake and genuine expertise brought to a test to help consumers make the right choices. The two are currently on sale in the market of the Motorola V680 battery, maybe you are using or to buy one, you know, what is the genuine batteries, battery, what is the fake? Counterfeiting is getting higher and higher standards, looks like two batteries, and the label affixed to almost the top, written by the technical parameters and attention to such matters are exactly the same as the average consumer it is difficult to distinguish from the pros to . Here's to take us to take a closer look at what the difference in the end.

Look at that picture above, of course, a good standard which is genuine and which is fake, you the impression that the most direct is a piece of silver, yes, this is to distinguish between the two most obvious way. But to know that just to find a fake, if more than a fake patch does this silver? This requires us to do various small compared more. Of course, this picture can illustrate that the fake anti-counterfeit labels above than than the genuine one, we can see the light of the security of the security tag is getting smaller and smaller, and, after all, this technology has been too many people in the hands of consumers(hp pavilion dv2000 battery, hp pavilion dv6000 battery, hp pavilion dv2500 battery) do not was too much confidence in these security tags.
