Lifepo4 Battery Pack

Introduction of lifepo4 battery pack 

Lifepo4 battery pack is a kind of 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 single unit is 3.2V, and the charge cut-off voltage is 3.6V~3.65V.

There are five types of Li-Ion cells on current market based on chemistry of cathode materials. Please see the table below to see the details of each type cell.

Working principle of lifepo4 lithium battery pack

During the charging process, part 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 are extracted 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. 

Advantages of lithium iron phosphate battery

Since Lithium iron phosphate material is more durable, safe, fast charging in characteristics,the Lifepo4 battery pack has following major advantages:

Higher Energy Density

Battery pack lifepo4 has about 1/3 the weight of lead-acid batteries.

Environmental Friendly

Lithium iron phosphate battery pack does not contain any metallic chemical, it has no environment pollution. 

Long Cycle-life

The 1C cycle life of Lifepo4 battery is even more than 3,500 times, and the energy storage market requires 4000-5000 times or more, guaranteeing a service life of 8-10 years.

Application of battery pack lifepo4

The LifePO4 battery pack is applicable for commercial or residential purposes.
