Li2S All Solid State Battery Raw Materials Anhydrous High Purity Lithium Sulfide

Lithium Sulfide Li2S All-solid-state Battery Raw Material Anhydrous High-purity Lithium Sulfide Purity 99.9%

Product Overview​​

Lithium sulfide (Li₂S, purity ≥99.9%) is a critical precursor material for sulfide-based solid-state electrolytes (SSEs) and lithium-sulfur (Li-S) batteries. As a white-to-yellow crystalline powder with an anti-fluorite structure, it enables ultra-high ionic conductivity (>10⁻³ S/cm) in SSEs like Li₆PS₅Cl and Li₁₀GeP₂S₁₂, while serving as a pre-lithiated cathode in Li-S systems.

Key Specifications​

​Material Advantages​​

1. ​​Solid-State Battery Performance​​

   • Enables SSEs with ionic conductivity rivaling liquid electrolytes (10⁻²–10⁻³ S/cm).
   • Reduces interfacial impedance in sulfide-based SSEs (e.g., Li₆PS₅Cl) by 50% vs. oxide alternatives.

2. ​​Lithium-Sulfur Battery Applications​​

   • Theoretical energy density of 2,600 Wh/kg (vs. 300 Wh/kg for NMC).
   • Pre-lithiated design eliminates need for external lithium sources.

3. ​​Industrial Scalability​​

   • Compatible with roll-to-roll (R2R) production for SSE membranes (20–40 μm thickness).
   • Cost projected to drop to $200/kg by 2030 (currently ~$480/kg).

Applications​​

• ​​Solid-State Electrolytes​​: Li₆PS₅Cl, Li₃PS₄, and LGPS-type SSEs.
• ​​Li-S Battery Cathodes​​: Li₂S@C nanocomposites (500+ cycles achieved).
• ​​Research​​: Prototyping of 500+ Wh/kg all-solid-state cells.
