Abstract
A method () for producing a sintered component being a solid electrolyte and/or an electrode including titanium and sulfur for an all-solid state battery, the method including mixing powders () so as to obtain a powder mixture comprising titanium and sulfur, pressing () a component with the powder mixture, sintering () the component under a partial pressure of sulfur comprised between 200 Pa and 0.2 MPa so as to obtain an intermediate sintered component comprising titanium and sulfur, and sintering () the intermediate sintered component under a partial pressure of sulfur equal to or smaller than 150 Pa at a temperature plateau comprised between 200° C. and 400° C. so as to obtain a sintered component comprising titanium and sulfur, the solid electrolyte exhibiting the peaks in positions of 2θ=15.08° (±0.50°), 15.28° (±0.50°), 15.92° (±0.50°), 17.5° (±0.50°), 18.24° (±0.50°), 20.30° (±0.50°), 23.44° (±0.50°), 24.48° (±0.50°), and 26.66° (±0.50°) in a X-ray diffraction measurement using CuKα line.
