Abstract
The present invention can provide a method for producing a sulfide solid electrolyte, the method characterized by including: a solution preparation step for preparing a uniform solution that includes at least elemental lithium (Li), elemental tin (Sn), elemental phosphorus (P), and elemental sulfur (S) in an organic solvent; a drying step for removing the organic solvent from the uniform solution to obtain a precursor; and a heat treatment step for heat-treating the precursor to obtain a sulfide solid electrolyte.
Claims7
A method for producing a sulfide-based solid electrolyte which comprises:
- preparing an Li3PS4-containing slurry;
- preparing an Li—Sn—S homogeneous solution that includes at least elemental lithium (Li), elemental tin (Sn) and elemental sulfur (S) in an organic solvent;
- mixing the Li3PS4-containing slurry and the Li—Sn—S homogeneous solution with each other to prepare a mixed slurry;
- removing the organic solvent from the mixed slurry to obtain a precursor;
- and
- heat-treating the precursor to obtain a sulfide-based solid electrolyte.
