Li2S Sulfurized Lithium 99.99% Solid Electrolyte Raw Material (< 5um)

This product is developed as a high-purity lithium sulfide (Li₂S) raw material for solid electrolyte synthesis in all-solid-state batteries (SSBs). With a measured purity of 99.997% and a fine particle size distribution predominantly below 5 μm (D50 ~2–3 μm), it offers consistent chemical reactivity and uniform mixing for sulfide-based electrolyte preparation. The material is supplied in a tightly sealed fluorinated container under inert gas to prevent moisture exposure, as it rapidly decomposes upon contact with air or water, releasing toxic hydrogen sulfide gas. All handling must be performed in an argon-filled glove box with O₂ and H₂O levels below 0.1 ppm. Given its high reactivity and associated hazards, appropriate personal protective equipment and safe storage procedures are essential. This Li₂S is primarily intended for research and development of sulfide solid electrolytes for next-generation lithium batteries.
