What is lithium iron phosphate battery

Lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate (LiFePO4) as cathode material and carbon as cathode material. The rated voltage of the single battery is 3.2V, and the charging cutoff voltage is 3.6V~3.65V.
During the charging process, some lithium ions in lithium iron phosphate are removed and transferred to the negative electrode through the electrolyte, which is embedded in the negative electrode carbon material; At the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit, maintaining the balance of chemical reactions. During the discharge process, lithium ions detach from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons, which reach the positive electrode from the external circuit and provide energy to the outside world.
Lithium iron phosphate battery has the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate, and no memory effect
