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