Universal A123 (iron phosphate)Power lithium batteryAnd power supply module

Belonging to A123 wanxiang group company is one of America's is committed to professional development, production of lithium ion battery and energy storage system of the company, the lithium ion battery with long service life, high energy density, high power, safety excellence can be ahead of the lithium ion battery market.A123 lithium battery products with lithium iron phosphate as battery cathode material, by making a uniform nanoscale (0.0002 microns) ultra small particles (now generally lithium battery cathode material particles, lithium iron phosphate grains compared to about 100 times), thus substantially improve the discharge of the battery power, A123Lithium iron phosphate batteriesCompared to the conventional lithium-ion batteries to release the electrical impulses at a speed of 10 times, and overall stability and cycle life are not affected.

A123 company mainly provides the lithium iron phosphate cathode material, main power lithium battery market at the same time, and the automotive lithium-ion batteries as a key development direction.A123 lithium ion products at the same time solve the influence power in high power lithium-ion batteries, safety and long life three aspects.

Tested on high power, A123 company said, in a plug-in hybrid developed in the battery pack, when the discharge depth under the condition of 100% after 3000 cycles, the battery pack can still maintain 90% of capacity.Lithium iron phosphate batteries in addition to being able to provide high discharge, A123 battery can also provide the energy fits.A123 has worked with the world's fastest Killa cycle electric motorcycle factory cooperation, to use 990 A123 battery core module (350 horsepower) set a speed of 257 km, 0-97 km speed record of 1.5 seconds.

A123 lithium battery in a day, on the basis of charge and discharge, which can realize continuous use for more than 15 years, even longer than the average car life.Learned, A123 lithium ion battery cathode material using in particle size small iron phosphate in right amount add carbon method, so as to improve the working life of the battery charge and discharge cycle characteristics.

In terms of safety, A123 for gm's Volt electric car designed by a group of cells (capacity of 16 KWH) can still work normally after extrusion failure test, other power lithium battery if the high-speed impact would overheat and catch fire.

At the same time, the use of A123 lithium battery hybrids, can further reduce most of the owners of gasoline demand, the demand of fuel gas can be reduced by 70%, while 50% can reduce carbon emissions, while reducing fuel consumption reduced to minimum impact on the environment.

At present, A123 company mainly provide AMP20 / square batteries, APR18650 AHP14 ANR26650 cylindrical battery (batteries) and AMP20 power supply module, starter battery 12 v / 48 v battery pack, etc.
