Iron Phosphate (FePO4) LFP Cathode Precursor
CAS Number: 7758-87-4
Battery-grade iron phosphate (FePO4) is the key precursor for LiFePO4 cathode synthesis, produced by co-precipitation of ferrous or ferric ions with phosphoric acid under controlled conditions. Ultra-low impurity levels, controlled particle size, and morphology directly determine the electrochemical performance of the final LFP cathode material.

Applications
- LiFePO4 cathode material synthesis (solid-state reaction with Li2CO3)
- Carbon-coated LFP nanoparticle production
- LFP for EV and ESS battery manufacturing
- Iron-based phosphate catalyst applications
- Battery precursor testing and R&D
Key Features
- Controlled co-precipitation produces uniform spherical morphology for consistent LFP sintering
- Low Ca, Mg, and Na impurities (<50 ppm each) prevents ionic conductivity degradation in LFP
- Fe/P molar ratio control (1.00±0.02) ensures stoichiometric LFP formation without Li2O excess
- Available in amorphous and crystalline forms for different LFP synthesis routes
