METHOD FOR PREPARING SOLID STATE ELECTROLYTE MEMBRANE STRUCTURE

A method for preparing a solid-state electrolyte membrane structure. The method includes: S proportionally mixing raw materials of a solid-state electrolyte to obtain a mixed powder; S mixing the mixed powder, a binder and a solvent together to obtain a solid-state electrolyte precursor slurry; S coating the solid-state electrolyte precursor slurry on a substrate to obtain a solid-state electrolyte precursor coating layer; and S subjecting the solid-state electrolyte precursor coating layer to a laser treatment to obtain the solid-state electrolyte membrane structure.
