Product Definition

Lithium iron phosphate cathode material, also known as LFP (Lithium Iron Phosphate) cathode material, is a positive electrode active substance used in lithium - ion batteries. This cathode material uses lithium iron phosphate as the main compound, usually with carbon material as the anode. The energy storage and release of the battery are achieved through the charging and discharging process.

The crystal structure of lithium iron phosphate cathode material is stable, endowing it with excellent cycle performance and safety. During the charging process, lithium ions are extracted from the cathode material, transferred through the electrolyte to the anode, and embedded in the anode carbon material. At the same time, electrons are released from the cathode to maintain the balance of the chemical reaction. During the discharging process, lithium ions are extracted from the anode, return to the cathode through the electrolyte, and give out electrons from the external circuit to provide energy to the outside. It is widely used in fields such as electric vehicles and energy storage systems. The mainstream preparation process of lithium iron phosphate is the solid - phase method, which includes the ferrous oxalate process, the iron phosphate process, and the iron oxide red process.
