Abstract
Provided herein are solid materials that are ionically conductive and electrochemically stable. Embodiments of the solid materials are argyrodite-type compositions that have high ionic conductivity. The compositions include small amounts of thiophilic metals, whose binary sulfides do not react with water to hydrogen sulfide (H2S). As such, H2S release is minimized or eliminated. Also provided are methods of fabricating the materials and batteries and battery components containing the materials.
