Investigating dry room compatibility of sulfide solid-state electrolytes for scalable manufacturing

Abstract

When exposed to moisture, Li 6 PS 5 Cl undergoes both hydrolysis and hydration reactions. It can be partially recovered by heat treatment, but hydrolysis causes the formation of LiCl, Li 2 S, Li 3 PO 4 , and oxysulfides due to the irreversible sulfur loss.
