Lithium iron phosphate batteries (LFP) are used in high-power applications, such as HEVs, EVs, and consumer electronics devices. They are rechargeable batteries that use iron phosphate as a cathode and carbon as an anode. Lithium iron phosphate batteries have good electrochemical performance and low resistance. The advantages of using these batteries include better thermal stability and safety, higher current density, and longer shelf life than other lithium ion batteries. This technology has an excellent deep-discharge cycle life that shields the battery from damage.
