Abstract: Provided herein are methods of preparing Li2S. The methods generally include combining an alkaline metal sulfide, a lithium salt, an alcohol, and a hydrocarbon to form a mixture. A reaction forms the Li2S. A dense solvent is then added to the mixture and the Li2S is isolated from the mixture.

Abstract: A solid electrolyte material comprises Li, T, X and A wherein T is at least one of P, As, Si, Ge, Al, and B; X is one or more halogens or N; A is one or more of S and Se. The solid electrolyte material has peaks at 17.8°±0.75° and 19.2°±0.75° in X-ray diffraction measurement with Cu-Kα(1,2)=1.5418 Å and may include glass ceramic and/or mixed crystalline phases.
