ABSTRACT:
A solid electrolyte containing a polymeric matrix, a salt, a solvent, and a toughening agent, is provided. The toughening agent may include alumina, silica, zeolite, and metal oxides (e.g., calcium oxide and magnesium oxide), and mixtures thereof. The toughening agent acts as a drying agent to remove excess solvent in the electrolyte. The solid electrolyte have improved mechanical strength and adherence to the anode and cathode.
