Lithium Iron Phosphate (LFP) Cathode Material LiFePO4
CAS Number: 15365-14-7
Lithium iron phosphate (LFP) is the safest, most cycle-stable commercial cathode, with a flat 3.2V plateau, no oxygen release, and thermal stability above 400°C. Carbon-coated LFP is the cathode of choice for energy storage, e-buses, grid applications, and low-cost EV platforms prioritizing cycle life (>3000 cycles) over energy density.

Applications
- Grid-scale energy storage system (ESS) cathode
- E-bus and commercial EV battery cathode
- Low-cost standard-range EV (BEV) cathode
- UPS and backup power battery cathode
- E-bike and light EV battery cathode
Key Features
- Excellent thermal stability (exothermic decomposition >400°C) for highest battery safety
- Long cycle life >3000 cycles at 80% DOD, ideal for ESS and fleet electrification
- No cobalt or nickel content reduces raw material supply chain risk and cost
- Compatible with aqueous and NMP-based binder systems for flexible manufacturing
