Abstract
Official abstract text for this publication.
A solid electrolyte material for a solid state battery ( 10 ) having the following chemical formula XM 2 (PS 4 ) 3 , where P is phosphorus, S is sulfur and X is lithium (Li), sodium (Na), silver (Ag) or magnesium (Mg 0.5 ) and M is titanium (Ti), zirconium (Zr), germanium (Ge), silicon (Si), tin (Sn) or a mixture of X and aluminium (X+Al) and exhibiting peaks in positions of 2θ=13.64° (±1°), 16.48° (±1°) and 22.18° (±1°) in a X-ray diffraction measurement using CuKα line, where I A is the intensity in arbitrary units of the peak at 13.64° (±1°) and I B is the intensity in arbitrary units of a peak at 23.34° (±1°), (I A −I B )/(I A +I B )>0. The disclosure is also related to a solid electrolyte comprising the solid electrolyte material and a solid state battery comprising the solid electrolyte.
