ABSTRACT:
A non-aqueous electrolyte comprises an aluminium halide and a quaternary ammonium halide dissolved in a non-aqueous solvent. A non-aqueous electrolytic cell is also described, which comprises an anode made of Al or its alloy, an cathode and the non-aqueous electrolyte provided between the anode and the cathode. The non-aqueous electrolyte is suitable for electrodeposition of aluminium from the electrolyte. Because aluminium is reversibly electrodeposited from and dissolved in the electrolyte, the electrolyte is usable for making secondary cells having good charge and discharge characteristics and a high energy density.
