Electrode Compatibility
- Stable with NCM811 cathodes (up to 4.3V)
- Minimal reaction with lithium metal anodes
Processing Flexibility
- Suitable for dry pressing (300-500 MPa)
- Compatible with tape casting (slurry formulation available)
- Optimal sintering temperature range: 900-1100°C
Packaging & Storage
