Product Description

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

Property	Value
Purity	≥99.9% (Battery Grade)
Crystal Structure	Cubic anti-fluorite (Fm-3m)
Particle Size	1–10 μm (laser verified)
Density	1.66 g/cm³
Melting Point	938°C
Impurities	Al/Ca/Fe/Ni/Pb/Se <100ppm

Performance Advantages

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
Air Sensitivity Mitigation
- Vacuum-sealed with argon protection (O₂/H₂O <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 <25°C
Processing:
- Ball-mill with P₂S₅ at 500 rpm for 10h (Ar atmosphere)
- Cold-press pellets at 300 MPa for conductivity testing
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.
