Product Description
Material Overview
Li₂S (Lithium Sulfide) serves as a critical precursor for synthesizing high-performance sulfide solid-state electrolytes (SSEs) including Li₇P₃S₁₁ and Li₁₀GeP₂S₁₂. With 99.9% purity and ultra-low impurity content (less than 100ppm total metals), this material enables researchers to develop next-generation all-solid-state batteries (ASSBs) featuring exceptional ionic conductivity exceeding 10 mS/cm and electrochemical stability ranging from 0-5V vs. Li⁺/Li.

Performance Advantages
Ultra-High Purity
- Minimizes side reactions with Li metal anodes (critical current density greater than 4 mA/cm²)
- Reduces interfacial resistance by 30% compared to 99% purity Li₂S
Air Sensitivity Mitigation
- Vacuum-sealed with argon protection (O₂/H₂O less than 0.1 ppm)
- Special handling protocols provided for glovebox transfer
Research Applications
- Synthesis of argyrodite-type (Li₆PS₅Cl) and LGPS-type electrolytes
- Direct use as cathode material in Li-S batteries (theoretical capacity: 1166 mAh/g)
Handling Protocol
Storage
Maintain in unopened packaging at temperatures below 25°C
Processing
- Ball-mill with P₂S₅ at 500 rpm for 10 hours (Ar atmosphere)
- Cold-press pellets at 300 MPa for conductivity testing
Safety
- H₂S gas risk during hydrolysis - use fume hoods
- Emergency neutralization kit recommended
Custom particle sizes (nanoscale to 50 μm) and doping packages (Ge/Ta/Sn) available for specialized research needs.
