1. A solid electrolyte material comprising:
Li, T, X and A, wherein T is at least one element selected from the group consisting of P, As, Si, Ge, Al, and B; X is one or more halogens or BH4, BF4, NH2, or NO3, or a combination thereof; A is one or more of S, Se, and N;
wherein the solid electrolyte material has peaks at 2θ=14.6°±0.25°, 15.3°±0.25°, and 25.1°±0.25° in an X-ray diffraction measurement with Cu-Kα(1,2)=1.5418 Å,
and wherein the solid electrolyte material has a Raman spectrum comprising a peak at 423 cm-1, wherein the peak at 423 cm-1 is the highest intensity peak in a range from 200-700 cm-1.
