METHOD OF PRODUCTION OF A SOLID LiPS-CONTAINING ELECTROLYTE Russian patent published in 2021 - IPC H01M10/562 H01M10/525 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of production of a solid electrolyte. The method of production of a solid Li₃PS₄-containing electrolyte includes: a stage of obtaining a solution wherein a homogeneous solution is obtained by mixing Li₂S and P₂S₅ in an organic solvent; and a precipitation stage wherein an additional amount of Li₂S is added and mixed with the homogeneous solution forming a precipitate. In the preferred implementation variant, the molar ratio (Li₂S/P₂S₅) between Li₂S and P₂S₅ at the stage of obtaining the solution equals 1.0 to 1.85, or such an additional amount of Li₂S is added to the homogeneous solution at the precipitation stage that said molar ratio becomes equal to Li₂S/P₂S₅=2.7 to 3.3.

EFFECT: technical result is excellent efficiency of the electrolyte and minimal possible content of byproducts.
