Abstract
A method for producing a solid electrolyte for an all-solid state battery, the solid electrolyte having the following chemical formula XM(PS), where X is lithium (Li), sodium (Na), silver (Ag) or magnesium (Mg) and M is titanium (Ti), zirconium (Zr), germanium (Ge), silicon (Si), tin (Sn) or a mixture of X and aluminium (X+Al) and the method including: mixing powders so as to obtain a powder mixture; pressing a component with powder mixture; and sintering component for a period of time equal to or greater than 100 hours so as to obtain the solid electrolyte. The solid electrolyte exhibits the peaks in positions of 2θ=13.64° (±1°), 13.76° (±1°), 14.72° (±1°), 15.36° (±1°), 15.90° (±1°), 16.48° (±1°), 17.42° (±1°), 17.56° (±1°), 18.58° (±1°), and 22.18° (±1°) in a X-ray diffraction measurement using CuKα line. The disclosure is also related to a method of producing a solid electrolyte.
