FIELD: chemical or physical processes.
SUBSTANCE: invention relates to a method of producing a solid electrolyte LGPS-type, having a specific crystalline structure, which includes Li, P and S. Method involves a dissolution step for preparing a homogeneous solution by mixing and reacting Li2S and P2S5 in an organic solution in such a way that molar ratio Li2S/P2S5 is 1.0–1.85; a precipitation step for forming a precipitate by adding to the homogeneous solution at least one MS2 (M is selected from the group consisting of Ge, Si and Sn) and Li2S and then mixing; a drying step for producing a precursor by removing the organic solution from the precipitate; and a thermal treatment step for producing a solid LGPS-type electrolyte by heating precursor at 200–700 °C.
EFFECT: excellent performance, stable performance, suppression of formation of by-products.
