Abstract: A solid electrolyte material comprises Li, T, X and A wherein T is at least one of P, As, Si, Ge, Al, Sb, W, and B; X is one or more halogens and/or N; A is one or more of S or Se. The solid electrolyte material has peaks at 14.9°±0.50°, 20.4°±0.50°, and 25.4°±0.50° in X-ray diffraction measurement with Cu-Ka(1,2)=1.5418 Å and may include glass ceramic and/or mixed crystalline phases.
