NOVELTY - The battery has a battery main body provided with a positive electrode and a negative electrode and filled with electrolyte i.e. acidic halogen aluminate ion liquid. The positive electrode is made of graphene/sulfur-containing polymer composite material or poly-benzene compound. The negative electrode is made of aluminum-containing metal or aluminum alloy material. The acidic halogen aluminate ion liquid is selected from organic salt-halide ion liquid, organic salt and aluminum halide e.g. aluminum chloride, aluminum bromide and aluminum iodide. USE - Secondary aluminum battery.
