The definition of the lithium iron phosphate battery

2021-11-18

Lithium iron phosphate battery is a lithium-ion battery using lithium iron phosphate (LiFePO4) as positive material and carbon as negative material. The rated voltage of the monomer is 3.2V and the charging cut-off voltage is 3.6V ~ 3.65v.

During charging, some lithium ions in lithium iron phosphate battery are removed, transferred to the negative electrode through electrolyte and embedded into the negative carbon material; At the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of chemical reaction. In the process of discharge, the lithium ion comes out of the main pole and reaches the positive pole through the electrolyte. At the same time, the negative pole releases electrons and reaches the positive pole from the external circuit to provide energy for 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.
