High Purity Lithium Sulfide Li2S Purity 99.9% Sulfide Solid Electrolyte

High Purity Lithium Sulfide Li2S Purity 99.9% Sulfide Solid Electrolyte Raw Material Lithium Battery Scientific Research Experiment

Material Overview​​

Li₂S (Lithium Sulfide) is a critical precursor for synthesizing high-performance sulfide solid-state electrolytes (SSEs) like Li₇P₃S₁₁ and Li₁₀GeP₂S₁₂. With 99.9% purity and ultra-low impurity content (<100ppm total metals), this material enables researchers to develop next-generation all-solid-state batteries (ASSBs) with exceptional ionic conductivity (>10 mS/cm) and electrochemical stability (0–5V vs. Li⁺/Li).

Key Specifications​​

Performance Advantages​​

1. ​​Ultra-High Purity​​

   • Minimizes side reactions with Li metal anodes (critical current density >4 mA/cm²)
   • Reduces interfacial resistance by 30% compared to 99% purity Li₂S

2. ​​Air Sensitivity Mitigation​​

   • Vacuum-sealed with argon protection (O₂/H₂O <0.1 ppm)
   • Special handling protocols provided for glovebox transfer

3. ​​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​​

1. ​​Storage​​: Maintain in unopened packaging at <25°C
2. ​​Processing​​:
   • Ball-mill with P₂S₅ at 500 rpm for 10h (Ar atmosphere)
   • Cold-press pellets at 300 MPa for conductivity testing
3. ​​Safety​​:
   • H₂S gas risk during hydrolysis – use fume hoods
   • Emergency neutralization kit recommended

Note: Custom particle sizes (nanoscale to 50μm) and doping packages (Ge/Ta/Sn) available for specialized research needs.
