lithium battery pack hybrid passenger
The battery procurement, Fukuda V buses currently used in Europe and Japan's Hitachi Vehicle Energy is the company's manganese lithium batteries. But it was said, Fukuda has also been with domestic battery manufacturers to cooperate, in June this year, will be loading experiments planned by 2010, began to domestic procurement lithium battery. Liu Guoqiang, but declined to disclose the grounds of commercial confidentiality for Which battery manufacturers. For vehicle manufacturers, since there was no pursuit of high profits, market share, competing on a prime objective. In a sense, who can take the lead in achieving new energy battery in the car on the industrial applications, who will be able to very favorable position. According to reports, Futian Automobile's new energy vehicles as part of a base is based on the company's existing real sector as the basis, in order to have been completed Fukuda Europe V 2 new energy bus project as the core, including hybrid electric, natural gas, liquefied petroleum gas, clean fuel and other departments. In addition, the FAW Group has also signed with the Dalian municipal government Sony Digital Camera Battery to build energy-saving and new energy production base for passenger cars strategic cooperation agreement which aims to reach 3000 in 2013 / year capacity. According to the China Statistical Information Network Bus statistics, as of November 2008, has 17 provinces (municipalities), more than 30 companies involved in hybrid passenger cars. Currently has hybrid technology, mainly Yutong Bus Company, Xiamen Golden Dragon, big Jinlong, FAW Group, Wuzhou dragon, Anyuan, Jinghua, Foton Motor, Dongfeng, Ankai, the pass and so on. Battle of the direction of lithium batteries According to the industrial chain, power batteries can be divided into the battery manufacturing and battery materials, finished products, parts manufacturing two types of enterprises, battery materials can be divided into lithium battery pack electrode (positive / negative) materials, separator and electrolyte. Li-ion battery cathode material is the core of the current lithium cobalt oxide, lithium manganese, lithium and nickel-cobalt-manganese-based lithium iron phosphate. Ze Yi graphite anode material, solid carbon particle-based; in the middle of positive and negative electrodes while the battery electrolyte and separator. Prior to this, the reason why the cost of lithium batteries is higher than nickel-metal hydride batteries, the main reason lies in its use of cathode materials based on precious metals as raw materials cobalt lithium cobalt oxide, lithium manganese oxide and lithium iron phosphate is more obvious because of cost advantages, is becoming The main development direction of lithium batteries

Sony Digital Camera Battery. That is, lithium battery pack, mainly in the battle of lithium manganese oxide and lithium iron phosphate started between. Although the nickel-metal hydride batteries because of technical maturity and cost advantages in the short term will remain a hybrid electric vehicle of choice for power, but because of its energy density is low and the memory effect of the shortcomings, in terms of cost is resolved, lithium batteries will become a net Electric cars and plug-in hybrid electric vehicle the main driving force option. Compared with the lithium manganese oxide, lithium iron phosphate capacity of the higher density, the former 100-115mAH / g, the latter 130-140 mAH / g; charge and discharge are living longer, the former is 500 times more than the latter up to 1500 times or more; operating temperature range greater, the former from 0 to 50 ℃, which was -40 to 70 ℃. The emergence of lithium iron lithium battery pack phosphate batteries, so that hybrid and pure electric vehicles, the development prospects of even more uncertain, because of its power, charging time and cost of follow-up to driving there is a big improvement. At the same time, the cost of lithium iron phosphate also lower than the lithium manganese oxide. But its fatal weakness is "conductive," Oh, now the mainstream technology to address this issue useful for conductive carbon-coated particles, using metal-oxide-coated particles, so particles with nanometer particles and so on. If the issue is effectively resolved, the great advantages of lithium iron phosphate will become a vehicle to promote their material of choice for battery. At present, the domestic lithium manganese battery production in the field, CITIC Guoan (000,839, stock bar) (000,839) research and development subsidiary Mengguli dynamic manganese lithium batteries, has passed the national security test, and after 2023 model run, a complete 2008 Beijing Olympic Games the only electric vehicle batteries. Lithium iron phosphate batteries, in addition to BYD, the BAK Battery, Inc. (NASDAQ listed company, code CBAK) are also produced. In addition, Xianyang deflection (000,697, stock bar) (000,697) holding power of a subsidiary of Xianyang g technology is relatively mature, but the lack of funding mass production. Fukuda Europe V Bus Technology Liu Jihong, deputy director, said Fukuda's hybrid bus using lithium manganese batteries reason why is because manganese lithium battery lighter lithium battery pack than the nickel-hydrogen battery technology is mature than the lithium iron phosphate batteries. It is understood that a hybrid bus in Europe V high-power lithium manganese batteries weighing about 200 kg less than the weight of a nickel-metal hydride batteries / 3. The industry believes that nickel-metal hydride battery is water, electrolyte is potassium hydroxide aqueous solution, the voltage canon NB-5H battery is only 1.2 volts, the entire system is very stable.
