About this material
LiFePO4 (LFP) is an olivine-structured cathode material built around an abundant iron-phosphate framework. Its strong P–O bond stabilises the lattice at full charge, which is why LFP cells tolerate abuse, overcharge and high temperature far better than layered oxides. The trade-off is a lower average voltage — 3.2 V against 3.6–3.7 V for NCM — and a lower pressed density, so cell-level energy density is moderated by design rather than by material limitation.
This grade is supplied for electrode slurry preparation in coin-cell, pouch and cylindrical builds. Particle size and carbon coating are tuned for uniform dispersion in NMP/PVDF systems; the material also runs in water-based carboxymethyl cellulose routes where the process calls for it. Typical laboratory loading is 2–4 mAh/cm² of coated area.
Documentation, controls and care
Quality controls
- Batch-level certificate of analysis with every shipment
- Moisture by Karl Fischer, reported per lot
- Magnetic impurity screening
- Retained samples held for 12 months
Handling & storage
- Store in a dry environment below 30 °C, away from direct sunlight.
- Equilibrate to room temperature before opening sealed packaging to avoid condensation.
- Dry at 60–80 °C under vacuum before slurry preparation where the process requires it.
