Lithium Iron Phosphate Battery (LFP)

LiFePO₄ ⇌ FePO₄ + Li⁺ + e⁻

نظرة عامة

LFP batteries use lithium iron phosphate cathode and graphite anode with a cell voltage of 3.2–3.3 V and energy density of 90–160 Wh/kg. The olivine crystal structure of LiFePO₄ provides exceptional thermal stability and safety — the Fe–O bond is much stronger than the Co–O bond in NMC/NCA, preventing oxygen release during thermal runaway.
