Abstract
Disclosed is a method of preparing a sulfide-based solid electrolyte for an all-solid battery having an argyrodite-type crystal structure through a solution process. The method including obtaining a precursor solution by dissolving lithium sulfide, phosphorus sulfide and a halogen compound in a solvent, obtaining a precursor powder by removing the solvent from the precursor solution. Solid electrolyte for an all-solid battery can be produced by such method.
