Abstract: A method of synthesizing a solid-state electrolyte where P2S5, Na2S and LiCl are dissolved in one of more solvents; where upon reacting of the mixture, NaCl precipitates out and is removed from the solution; the solvent is removed; and the sulfide solid-state electrolyte is dried, then crystalized to be used in a solid-state battery. A solid-state battery comprising the produced sulfide solid-state electrolyte is also described.

Abstract: A solid electrolyte material comprises Li, T, X and A wherein T is at least one of Sb, P, As, Si, Ge, Al, and B; X is one or more halogens or N; A is one or more of S or Se. The solid electrolyte material has peaks at 2θ=14.5°±0.50°, 16.8°±0.50°, 23.9°±0.50°, 28.1°±0.50°, and 32.5°±0.50 in X-ray diffraction measurement with Cu-Kα(1,2)=1.54064 Å and may include glass ceramic and/or mixed crystalline phases.
