Details
Open under inert gas protection, use in a dry and ventilated environment, avoid contact with acids, pay attention to personal protection, and treat waste containing lithium sulfide with alkali.
Lithium sulfide is relatively stable at high temperatures, but it absorbs water and releases hydrogen sulfide in air.
When heated to 300 ℃ in air, it oxidizes to form lithium sulfate, which reacts with sulfur to produce polysulfides.
It is used as a raw material for sulfide solid-state battery electrolytes or as cathode electrode material for lithium
sulfur batteries in batteries
