Product Description
Product Overview
Lithium Sulfide (Li₂S) with purity ≥99.9% is a critical precursor material for advanced battery technologies. This white-to-yellow crystalline powder with anti-fluorite structure enables ultra-high ionic conductivity exceeding 10⁻³ S/cm in solid-state electrolytes and serves as a pre-lithiated cathode material in lithium-sulfur battery systems.
