What is the cathode material of lithium iron phosphate batteries?

[ZaneFitz]

The cathode material of lithium iron phosphate batteries is lithium iron phosphate, while the anode material is carbon. During the charging process, some lithium ions in the lithium iron phosphate are extracted, transported through the electrolyte to the anode, and embedded in the anode carbon material. Simultaneously, electrons are released from the cathode and travel through the external circuit to the anode, maintaining the balance of the chemical reaction. During the discharge process, lithium ions are extracted from the anode, travel through the electrolyte to the cathode, while the anode releases electrons that travel through the external circuit to the cathode, providing energy to the external circuit. Lithium iron phosphate batteries offer advantages such as high working voltage, high energy density, long cycle life, excellent safety performance, low self-discharge rate, and no memory effect.
