wholesale 12.8V 50Ah LiFePO4 Battery DIMENSION SPECIFICATION

Basic introduction of LiFePO4 battery:

HB1240 wholesale USP power Basic introduction of LiFePO4 battery

LiFePO4 battery

The LiFePO4 battery is a lithium ion battery using LiFePO4 as the positive electrode material and carbon as the negative electrode material.

During the charging process, some of the lithium ions in the lithium iron phosphate are extracted, transferred to the negative electrode through the electrolyte, and 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 to maintain the balance of the chemical reaction. During the discharge process, lithium ions come out from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy for the outside world.

Lithium iron phosphate batteries have the advantages of high working voltage, high energy density, long cycle life, good safety performance, low self-discharge rate and no memory effect.
