1. A method for plasma modification of sodium super ionic conductor type solid electrolyte, wherein the method comprises following steps:
plasma modification, the plasma modification comprising a solid electrolyte particles of sodium super ionic conductor being modified by dielectric barrier discharge plasma to obtain an activated sodium super ionic conductor type solid electrolyte particles; and preparation of composite solid electrolyte, the preparation of composite solid electrolyte comprising: a step of weighing polymer and the activated sodium super ionic conductor type solid electrolyte particles in a predetermined ratio, a step of dissolving the polymer and the activated sodium super ionic conductor type solid electrolyte particles in an organic solvent to obtain a mixed solution, a step of pouring the mixed solution into a predetermined mold, a step of drying to remove the organic solvent and forming into a composite solid electrolyte film; and a step of taking the composite solid electrolyte film out of the predetermined mold and rolled to obtain a roll-treated composite solid electrolyte film. |
