Abstract: A method for preparing a solid electrolyte is described. The method involves mixing a solid electrolyte selected from among sulfides with an agent comprising at least sulfur, adding the mixture obtained to an organic solvent, and then recovering the resulting solid electrolyte. The method may be used to form the solid electrolyte as a separator for a battery cell.
