U.S., rechargeable battery market
Market research firm Freedonia Group, said, cell phones laptop battery, PDAs and emerging wireless devices in the next five years will be to promote the growth of rechargeable battery market. The world of non-rechargeable lead-acid batteries sold in 2006 from 2001 to 101 billion dollars to 162 billion U.S. dollars. In the U.S., rechargeable battery market in 2005 from 2001 to 25 billion dollars to 42 billion U.S. dollars.
Freedonia analyst Ken Long said the growing demand for rechargeable batteries is that notebook computers, handheld computers and mobile phones such as the popularity of portable electronic equipment. He pointed out that the use of digital cameras and multi-function sony battery handheld computers and other power-electronic products will increase battery. Most of these applications use lithium-ion batteries.
Long said the lithium-ion batteries will be the product of choice in many applications because such products can provide a longer working hours. However, lithium-polymer battery will also get some market share because the battery is flexible, portable devices can be made a special space.
Long pointed out that in 2001, 34% of rechargeable batteries are lithium-ion vgp-bps8, vgp-bpl8 battery. In 2005, this figure will increase to 45%. Lithium-polymer battery market share from 2000 to about 2% to 10%.
Used in electric tools, and some low-end portable electronic devices nickel-cadmium batteries will lose market share. In 2000, nickel-cadmium batteries can be Chong Chongdian battery market accounted for 35% of the market. By 2005, nickel-cadmium battery market share will drop to 16%. For low-end mobile phones and handheld game consoles nickel-metal hydride batteries will maintain 15% market share.
On the Sanyo, Panasonic, Toshiba, and Rayovac batteries and other manufacturers, the main challenge is the production of smaller batteries and increase battery life. Another problem is to reduce the battery charging time.
Earlier this year, Rayovac Corporation announced the I-C3 technology. Just 15 minutes of this technology can be finished for the battery charge power. The technology to put the battery charge function, rather than inside the charger. In this way, the battery charging time is not only short and full power. This vgp-bps9, VGP-AC19V13 battery can be charged 1,000 times. However, the price of the battery than the battery does not use this technique more expensive.
Surge in demand for non-ferrous metals market, a tight lead-Star
China's auto industry's rapid growth and the rapid development of lead-acid battery industry is to lead the greatest driving force behind rising prices.
Because of supply tensions, lead to become the most promising varieties of non-ferrous metals. Many agencies predicted that London's lead in the third quarter of 2007, futures prices will be new vgp-bps5a record high.
All along, China is the world's largest lead-producing country, a huge long-term export prospects for the market price of lead rather pessimistic. However, authorities said Monday this year, June 1, the adjustment of import and export tariff rates for some commodities, including refined lead exports of tax of 10% tax rate, it enables investors to significantly slow breath.
World Bureau of Metal Statistics (WBMS) Wednesday said that this year will be the fujitsu battery fifth year in short supply, where this year alone a quarter of the global lead market supply deficit will be up to 77,000 tons.
22, the London Metal Exchange 3-month lead reached 2215 U.S. dollars / ton historical record, more than the beginning, the price has risen by 23%.
Lead is mainly used for manufacture of automotive batteries, while the Chinese auto industry's rapid growth and the rapid development of lead-acid battery industry is to lead the greatest driving force behind rising prices. Morgan Stanley estimates that China's auto sales last year, lifebook t4220 battey, lifebook p1510 battery year on year increase of 40%.
In addition, the supply can not keep up the pace of demand growth has always been. Magellan lead mine in Australia had to stop production due to an accident 3-4 months, together with other galena from time to time of production failure, prompting the International Lead and Zinc Research Organization (IZLSG) to adjust the supply of vacancy 50,000 tons, while the recent also predicted that supply and demand will be basically flat. National Australia Bank (NAB) analyst Gerard Burg said the most optimistic estimate is 2008, Indonesia and Bolivia Series Lead Mine production, the global lead market, supply and demand balance is possible.
Currently, LME lead stocks fell more than last year by 60%, the current level just enough for two days of global consumption.
China's refined lead to improve the impact of export duties, senior analyst with Beijing Antaike Jun Feng from the view that the short term, although the elimination of the market's concerns about China's massive exports, but in the long term risks still exist lifebook p7120 battery. She said in April China's refined lead production increased by 11.7%, 1-April increased by 5.9%. Output growth and domestic lead prices down is the ultimate incentive to manufacturers to the international market for sales. "Short-term, the export of refined lead might not be profitable, while the long term, lead to overproduction and the international price is relatively higher than that of domestic exports will once again lead to the climax."
Lead is also the most promising investment guru Jim Rogers of non-ferrous metal species, which he called "a potential fly heavy metal." He pointed out that other commodity prices in recent years, few hotter than the price of lead, even if the lead industry in the past 20 years, lost the two largest markets - the case of paint and gasoline are still without prejudice to its record high, which is Over the same period of tighter supplies and rising demand response. He predicted that once the count inflation, lead prices will rise higher, because the supply is declining and demand is increasing. He even said that even if demand falls, the lead market is still likely to be a huge bull market. Because a drop in demand, and even economic slowdown does not necessarily mean that a bear lifebook t4210 battery, FPCBP155 fujitsu battery market - if a more severe decline in the supply of words.
National Indoor Stadium
Recently, the construction work undertaken by the Beijing Urban Construction Group National Stadium Digital Camcorder Battery project to install solar cells imported from Germany, glass curtain, marking the National Stadium, 100-kilowatt grid-connected photovoltaic project entered the installation phase. National Indoor Stadium will be installed 1148 solar cells, this is the first in the Olympic project to install solar projects. After the completion of the design every day to reach 100 kW rated power output, grid-added to the low-voltage distribution system, 20,000 square meters for underground lighting.
Battery cell also rose in July, the new universal benefit Shunda
Battery cell raw material prices, driven BP-511 battery prices, Taiwan's Department of battery factory yesterday (24) said that this year will be rising for battery cells in two waves, this month gone up anywhere, but also has another one in July. In addition, the second half of the battery core shortage problem is serious, whether the sources of material to grab the battery core stability, it will be able to dramatically the battery assembly plant growth in revenue key.
Two batteries of domestic assembly plants in the new P (6121) and Shun (3211) yesterday, have said that as the close cooperation with the CR-V3 battery cell maker, battery cell supply will not be a problem, but the second-line plant in the second half is likely to face shortage of supply of .
While the battery cell in prices, but has been completely passed on to the battery pack prices, price increases for some products is also higher than the battery cell increases, the situation on the new Pu, Shunda and other battery plant favorable, traders said that the future would depend on the raw materials for costs continue to adjust prices.
Pu Song Fuxiang be held before the new chairman of France said they would, said that the battery core prices will rise, in fact, the battery core prices have increased this month, a wave, AM about 5% to 8%, due to the battery core materials include cobalt, nickel prices , and the gains almost doubled, and the klic-5001 battery core is expected to hike prices again in July, up 5% to 6%.
Battery cell supply to Japan, South Korea-based manufacturer, which rises in Japanese Sanyo has announced that 5-8%, Samsung SDI was jumped 7% to 10%, while the Japanese giant Sony announced plans starting from next month on the 1st follow-up hike, AM is also around 5-8%.
This year notebook shipments in terms of 9,500 million units, or even could reach 100 million units, the battery core from last year's Sony battery recall incident, continued tight supply, the second half of this year came during the peak season effect, the battery would be great lack of core goods, batteries, EN-EL3e battery assembly plant must master the core source of revenue recorded a chance Suibi increase in PC shipments to grow.
Prices, Wuxi excess production capacity batteries for export face challenges
As mobile phones, digital cameras, camcorders, laptops, electric cars and other consumer products, the continued strength of domestic battery is a lithium-ion batteries in particular, has shown great potential for applications, but also for export provided the impetus for robust growth. As of April 2007, in Wuxi, Jiangsu Province, were exported from the EN-EL4 battery 5116 batches of up to 310 million U.S. dollars export value, compared with the same period last year, an increase of 33.75%, respectively, and 36.78%.
Wuxi region's exports from the terms of types of batteries, lithium-ion battery products accounted for 80% of the total export volume over. In recent years, Sony and Panasonic, respectively set up production base in Wuxi, allowing the export of Wuxi in the Li-12B battery form a strong pull. From the mode of trade point of view, the battery in Wuxi-based exports, mainly to processing, the main exports to the Free Trade Zone and the Hong Kong and Taiwan, as well as Japan, the European Union and the United States. At present, the Wuxi area exports of lithium-ion batteries show the fast-growing momentum at the same time, there also exist some much-needed solution.
First, continued growth in demand, prices continued to decline. Lithium-ion batteries a mature market price to more than 15% average annual rate of decline. The second is excess capacity. Wuxi area the size of the battery industry due to rapid growth of production, have produced an oversupply in the market, leading to falling product prices, affecting economic growth in the industry. As the lithium-ion battery production plans and the upgrading of digital products have a very close relationship, with the digital products continues to introduce new lithium-ion Klic-7004 battery production plans have changed. Third, raw material costs. Since the second half of 2004 has been a sharp rise in world oil prices caused the rise of related chemical materials, particularly polymers. The ordinary chemical material compared to 2003, there are about 50% of the price rise, in which chemical solvents rose more than 70%. This state of affairs led many manufacturing polymer lithium-ion battery production enterprises have to face the issue of rising production costs.
The good news is, at present, the battery plant in Wuxi in new product development and upgrading of the faster, new products accounted for 40% of the total, in the battery industry have a certain competitive advantage. The battery product rational structure, most of them are environmentally friendly batteries, are therefore subject to the impact of the EU Directive pairs of green also less. But battery companies still vigilant. First, we must increase research and development for specialty Minolta NP-500 battery products, some thin battery or larger capacity battery development in order to give full play to polymer lithium-ion battery expertise and advantages.
As the polymer lithium-ion battery, which uses flexible packaging material, the mold shell is relatively simple, low cost, easy-to-change type, can be completely customized to user needs with the production, and timely conversion model, to respond quickly to market demands, in order to thin battery and large-capacity battery to create the conditions for the development. Second, enterprises should actively adopt new materials to reduce production costs or increase battery battery cost. At present, the polymer lithium-ion battery production in the main materials - positive and negative materials, accounting for more than half of the total cost of the battery, the production enterprises should actively explore new techniques and recipes battery such as NB-2LH , NB-4L , NP-20 , NP-30 , NP-BG1, ingredients and processes through the integration of the development of safe and reliable, affordable alternative materials to reduce battery costs, increase market competitiveness.
USB interface
Universal mobile phone charger and the public manufacturers
Updates on the mobile phone Digital Camera Battery market, more and more frequent, some consumers and even a year for a cell phone. For a cell phone, charger must follow words, they could not bear to throw out the charger, Retention not yet available, only let it lie quietly in a drawer. Last year in December, the State Ministry of Information Industry issued a recommendation on the cell phone charger standard, tried to use a uniform standard to address DSLR Battery Grip the mobile phone charger with each other can not be a common problem.
According to the plan, mobile phone universal battery charger available in May, but the reporters Gome and Suning sales outlets such as shopping malls where mobile phones do not have to find such a universal charger for sale. Finally, Shanghai Road, a mobile phone accessories store, the reporter found a universal cell phone chargers, store managers told reporters that such a universal charger have recently start to appear on the market in Dalian, but rarely interfere.
According to reports, this is a kind of universal charger converter, through the USB female seat attached a Nikon MB-D80 Battery Grip USB data cable to mother seat with power or computer connections, to realize mobile phone charging. However, due to the current phone models on the market numerous Wuza, there is still a small number of cell phone USB interface, so this universal charger can only serve a small number of models.
Yesterday, Bird cell phone customer service department told reporters, "At present, mobile phone universal charger Bird has entered the market, this year out of 18 Bird of new mobile phone models support this new charger." But customer service staff also stressed that the waveguide universal charger can only be a handful of several other brands of mobile phone charging. It is understood that at present there are 56 domestic handset manufacturers launched its own universal Nikon MB-D200 Battery Grip, but are also only use a few models, and some well-known international mobile phone manufacturers simply indifferent to the uniform standards, and no action.
Domestic brand mobile phone dealers Liu told reporters that, once a unified interface standard for mobile phone designs will adversely affect the appearance, so that vendors were not enthusiastic. Every mobile phone model of foreign standards are unified, single standard in order to meet the design of new Chinese mobile phone models unlikely. It is understood that the present pre-certified, can be matched with the universal cell phone charger is less than 10 models, mostly domestic brands, so even if consumers can buy in the market, Universal charger, the vast majority of people are still unable to benefit from , cell phone charger you want to "universal", have to wait.
A unified interface, mobile phone charger standard should be "enforced"
A unified interface, since the promulgation of the standard mobile phone charger, has launched a succession of products that meet standards come out, but the strange thing is most of Jiangshan foreign market-branded mobile phone manufacturers have not done! I think one of the key is this Sony VG-B30AM Battery Grip,Sony Alpha A200 Battery Grip standard is only the "Recommended Standards"!
The introduction of this standard, from the proposed topic, research, feasibility studies, drafting, for comments before it is finalized, official promulgation has experienced a six-year-old, in fact, not high-tech charger, giving a variety of battery-charging IC, and even solutions are readily available, and supposedly benefits the country and the implementation of such a standard How difficult can that be? Why are these foreign brands and mobile phone manufacturers to Wang gave the it? The truth is the "benefit" and the word trouble! Cheng Si ten-dollar cost of a charger, but if the title hung brand, the less have fifty or sixty, and then your perfectly normal! Can see that foreign brands is not easily give up this temptation.
We introduce this benefits the country and standards, both conservation and environment-friendly, and now charger USB charger interface is installed in the side, so the design of the terminal does not have any effect (which was their excuse for an opposition), foreign brands, there is no reason to fail to implement this standard!
The latest data, foreign brand's market share has reached 65% market share in most, if not the implementation of this standard product, then we are, what the meaning of this standard? Rose to even higher level, the standard is also reflected in national sovereignty, foreign brand-name products sold to the Sony Alpha A300 Battery Grip, Sony Alpha A350 Battery Grip Chinese market, we should abide by the provisions of the standard implementation of China! Can we allow the seven countries the system of eight products in the Chinese run wild?
Therefore, a unified interface, cell phone charger standard should be "to enforce standards".
Power battery: 4 years even out the 10-year gap
Power battery: 4 years even out the 10-year gap
"Tenth Five-Year" period, the national 863 Program of electric vehicles in major projects, set up a research fru 08k8193 battery, ibm thinkpad r50 battery, ibm thinkpad r51 battery power, this is the electric vehicles practical constraints of one of the key technologies.

"The first hybrid electric vehicle is expected to achieve industrialization, therefore, we will be hybrid electric vehicle (HEV) batteries with high power motivation as the focus of the study. The study was still a blank in China. So each of its technological advances have innovative. "Wu said.
Issues prior to the implementation of China's nickel-hydrogen batteries the maximum power density of only 230 watts per kilogram (W / kg), can not meet the basic HEV battery performance requirements. At that time, Toyota's hybrid Prius sedan has been the first volume in the international market, it is used for nickel-hydrogen batteries power batteries.
"High-power batteries power the key to solving the current problem of charging and discharging." Wu explained that the hybrid vehicle in motion a continuous process of charge and discharge. In the start-up, the need to accelerate the large current discharge, this car on the fast speed; braking, the energy feedback can be high current charge. "Nickel-hydrogen battery to increase power density, has become an important indicator of the study."

Special inspection at the meeting, many of the relevant data at home and abroad to convince the experts.
Not only that, a special technology in the battery, the electrode preparation process matures, have been completed and nickel hydrogen batteries and battery production line electrode assembly lines, with a production capacity. At present, the nickel-hydrogen batteries have been used in the operation of dozens of model cars and hybrid electric bus.
Li-ion battery safety significantly increased
Lithium-ion is relatively lively, security is the driving force for lithium-ion battery technology research difficult. Despite the current battery power in the international arena have not yet entered the commercial stage, but the technology as an important direction has been made a lot of research and development results and test-like vehicles. Press conference from the acceptance that the implementation of the adoption of the subject, China's Li-ion ibm thinkpad t40p battery, ibm thinkpad t41 battery, ibm thinkpad t41p battery technology has made considerable progress in the security and power density of significant progress, not only with the narrow gap between the advanced international level, and a number of performance has been able to better meet the test specifications.
According to Wu, the implementation of the subject, carried out power lithium-ion battery research and development of key materials to study the safety of electrolyte additives on performance of the battery, self-developed lithium manganese spinel materials for lithium-ion battery has power the development of materials provides protection. Annual production capacity of 150 tons of modified spinel lithium manganese oxide production line to address the high power a vehicle battery power supply of the cathode material, thereby significantly improve the safety of the battery.
In recent years, research and development group, a thin film electrode preparation technology, so that the passing rate of the electrode film has increased; power battery cathode mechanized envelope design process, reduces the powder away from the electrode caused by the internal battery the possibility of short circuit and high-pressure protective measures taken to ensure safety.
In equipment development, the group developed intermittent reversal of 800mm Coater滚涂accuracy of ± 1.5%, to become the most wide painted Chinese-made lithium-ion battery wiring, battery power for the realization of production equipment in China to lay the technical foundation.
And "973" basic research projects in close cooperation group has also developed a safe, low cost, environmentally friendly lithium-ion battery cathode material lithium iron phosphate ---. Lithium iron phosphate so that the electronic conductivity of materials in particular have improved significantly, but also the practical application of this material to lay the technical foundation.
It is reported that since the implementation issues, HEV with high-power lithium-ion battery power and improved safety. By the end of 2002 the concentration in the test, the lithium-ion batteries power a very serious security issue, or fire or explosion, without a battery test unit through security testing. After several years of efforts, by 2005, to participate in sampling of HEV Li-ion battery power through a safety inspection, there was no explosion, fire phenomenon, which for a lithium-ion batteries power the importance of the application.
Supercapacitor application has entered the field of
Supercapacitors lies between batteries and conventional capacitors of a new type of energy storage devices, in China less than 10 years. The implementation of the subject, respectively, with the fuel cell city bus and JIEFANG hybrid city bus to the super-capacitor research and development, focusing on the key materials ibm thinkpad t42 battery, ibm thinkpad t42p battery, structural design, manufacturing processes and management systems to initiate a technical research, the research has made important progress.
