Abstract
A method of making the sulfide-impregnated solid-state battery is provided. The method comprises providing a cell core that is constructed by cell unit. The cell core is partially sealed into the packaging such as the Al laminated film and metal can. The method further comprises introducing a sulfide solid-state electrolyte (S-SSE) precursor solution in the cell core, the S-SSE precursor solution comprises a sulfide solid electrolyte and a solvent. The method further comprises evaporating the solvent from the cell core to dry the cell core to solidify the sulfide-based solid-state electrolyte within the cell core and pressurizing the cell core to densify the solid sulfide-base electrolyte within the cell core. The cell core is then fully sealed.
