What is lithium iron phosphate battery?

It is a lithium-ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. 

The rated voltage of the cell is 3.2V, and the charging cut-off voltage is 3.6V~3.65V. 

During the charging process, some lithium ions will be released from the lithium iron phosphate, 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 will escape 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 to the outside world.

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

In addition to high output voltage, good safety performance, long life, fast charge and discharge, superior high temperature performance, no memory effect and green environmental protection, lithium iron phosphate batteries also have some other features:

Wide temperature range: Lithium iron phosphate batteries can operate normally within a wide temperature range of -20°C to +55°C, adapting to the needs of use in different environments.

High-temperature storage: Due to its good safety performance and superior high-temperature performance, lithium iron phosphate batteries can be stored in high-temperature environments without worrying about battery safety issues.

Green and environmentally friendly: The raw materials of lithium iron phosphate batteries are non-toxic phosphoric acid, lithium and iron. No toxic and harmful substances will be produced during the entire manufacturing and use process, and there will be no harm to the environment and human health.

Reusable: Lithium iron phosphate batteries have a long cycle life. After multiple charges and discharges, the battery performance still maintains a high level and can be reused many times.

Generally speaking, lithium iron phosphate batteries have excellent performance and characteristics and have broad application prospects in various application fields.
