　　Wanxiang A123 (iron phosphate) power lithium battery and power source module

　　A123 Company, a subsidiary of Wanxiang Group, is an American company dedicated to the professional development and production of lithium-ion batteries and energy storage systems. Its lithium-ion batteries are ahead of lithium-ion batteries with long life, high energy density, high power and excellent safety. battery market. The A123 lithium battery product uses lithium iron phosphate as the battery cathode material. It is manufactured into uniform nanoscale (0.0002 micron) ultra-small particles (currently general lithium battery cathode material particles are about 100 times larger than lithium iron phosphate particles), thereby significantly By increasing the discharge power of the battery, the A123 lithium iron phosphate battery can release electrical pulses 10 times faster than conventional lithium batteries, without affecting the overall stability and cycle life of the battery.

　　A123 Company mainly provides lithium iron phosphate cathode materials. It also focuses on the power lithium battery market and regards automotive lithium batteries as its key development direction. A123 lithium-ion products simultaneously solve the three problems affecting power lithium batteries in terms of high power, safety and long life.

　　In terms of high power, A123 Company has tested that in the battery pack developed for plug-in hybrid power, when the depth of discharge reaches 100%, the battery pack can still maintain 90% of its capacity after 3,000 cycles. In addition to providing high discharge, the lithium iron phosphate battery can also provide bursts of energy. A123 has cooperated with KillaCycle, the world's fastest electric motorcycle manufacturer, to use a battery module using 990 A123 battery cells (equivalent to 350 horsepower) to set a world record of 257 kilometers per hour and 0-97 kilometers acceleration in 1.5 seconds.

　　The A123 lithium battery can be used continuously for more than 15 years based on daily charging and discharging, which is even longer than the life of an average car. It is understood that the A123 lithium-ion battery cathode material uses a method of adding an appropriate amount of carbon to iron phosphate with very small particle size, thereby improving the battery's charge and discharge cycle life characteristics.

　　In terms of safety, a set of batteries (capacity 16kwh) designed by A123 for the General Motors Volt electric vehicle can still work normally after the crushing and destruction test. Other power lithium batteries will overheat and catch fire if they are subjected to such high-speed impact.

　　At the same time, hybrid vehicles using A123 lithium batteries can further reduce the gasoline demand of most car owners. The demand for gas fuel can be reduced by 70%, and carbon emissions can be reduced by 50%. While reducing fuel consumption, it is also harmful to the environment. The impact is reduced to a minimum.

　　At present, A123 Company mainly provides AMP20/AHP14 square batteries, APR18650/ANR26650 cylindrical batteries (cells), AMP20 power source modules, 12V starter batteries/48V battery packs, etc.
