Liquid-phase synthesis using water as a solvent with low environmental impact was demonstrated to synthesize sulfide electrolytes. LiGePS was successfully synthesized and exhibited an ionic conductivity of 7.7 × 10 S cm at 25 °C.

The glass-forming region of the ZrF-BaF system obtained using the mechanochemical method was wider than that obtained using the conventional melt-quenching method. The glass-ceramic 60ZrF·40BaF (mol%) sample was obtained by heat treatment and shows a higher conductivity of 1.

Sulfide active materials exhibit high capacities and enable an enhanced energy density in all-solid-state batteries. In this study, we synthesized electrode-electrolyte bifunctional materials in the system LiS-VS-LiX (X = F, Cl, Br, or I) through a mechanochemical process.
