Lithium iron phosphate

Lithium iron phosphate, written as LFP or LiFePO4, is a lithium-ion cell chemistry used in battery energy storage systems. It is also called lithium ferrous phosphate. LFP cells can charge and discharge reliably and quickly, which utility storage applications require. Their cycle life and application life are longer than those of other common lithium-ion chemistries. A wide operating temperature range, thermal stability, safety and environmental friendliness are the reasons the manufacturer calls LFP the best chemistry for utility energy storage.
