nowadays Lithium iron phosphate battery has been use for electric car gradually ,which have replced the prevous lead acide battery .
Lithium iron phosphate battery refers to the lithium ion battery which USES lithium iron phosphate as the positive electrode material. The anode materials of li-ion batteries mainly include lithium cobalt, manganese, lithium nickel, ternary materials and lithium iron phosphate. Among them, lithium cobalt acid is the positive electrode material used in most lithium ion batteries.
As the requirements of the rechargeable batteries are: high capacity, high output voltage, good charge and discharge cycle performance, stable output voltage, large current charge and discharge, electrochemical stability, use of safety (did not charge, discharge and short circuit caused by improper operation, such as the combustion or explosion), wide working temperature range, non-toxic or less poison, no pollution to the environment. Adopting LiFePO4 as anode of lithium iron phosphate batteries are good on these performance requirements, particularly in large discharge rate discharge (5 ~ 10 c discharge), stable discharge voltage, security, not burning, not an explosion, and life (cycles), on the environment pollution-free, it is the best, is currently the best large current output power battery.
