METHOD FOR MANUFACTURING A SOLID SULFIDE ELECTROLYTE

The present invention relates a method for manufacturing a solid sulfide electrolyte and the solid sulfide electrolyte obtainable from said method. The present inventors surprisingly have found that by mixing of the solid electrolyte precursor mixture with an organic liquid other than ethanol or methanol followed by heat-treating affording the solid sulfur electrolyte, the resulting conductivity of the solid sulfur electrolyte is higher.
