Abstract
A method for producing a sulfide solid electrolyte includes: 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; removing the organic solvent from the uniform solution to obtain a precursor; and heat-treating the precursor to obtain a sulfide solid electrolyte.
Claims18
A method for producing a sulfide-based solid electrolyte which comprises:
- preparing a homogeneous solution that includes at least elemental lithium (Li), elemental tin (Sn), elemental phosphorus (P) and elemental sulfur (S) in an organic solvent;
- removing the organic solvent from the homogeneous solution to obtain a precursor;
- and
- heat-treating the precursor to obtain a sulfide-based solid electrolyte.
