Material Advantages
Superior Ion Transport
- 3D diffusion channels enable near-liquid conductivity
- Low activation energy (0.2-0.3 eV) for stable low-temperature performance
Electrochemical Stability
- Compatible with Li-metal anodes (>2 mA/cm² CCD)
- Minimal interfacial resistance with NCM/LCO cathodes
Structural Characteristics
- Tetrahedral (PS₄)³⁻ and octahedral (GeS₄)⁴⁻ coordination
- Isotropic Li⁺ migration pathways
Handling Protocol
Storage
- Maintain in argon glovebox (O₂/H₂O
- 1-year shelf life in original packaging
Processing
- Cold press at 300-400 MPa for pellet formation
- Avoid water/oxygen exposure during cell assembly
Safety
- H₂S generation risk if hydrated - use fume hoods
Applications
- All-solid-state Li batteries (400+ Wh/kg prototypes)
- Hybrid electrolyte systems
- High-energy-density cell research
Note: Germanium scarcity impacts cost; alternatives available upon request. Manufactured by Kelude with ISO-certified quality control.
