▎ 摘　　要

NOVELTY - An aluminum secondary battery comprises anode, cathode, porous separator electronically separating anode and cathode, and electrolyte in ionic contact with anode and cathode to support reversible deposition and dissolution of aluminum at anode. Anode contains aluminum metal or aluminum metal alloy as anode active material; and cathode comprises a layer of aligned or oriented graphene sheets that are oriented in such a manner that the layer has a graphene edge plane in direct contact with the electrolyte and facing the separator. USE - An aluminum secondary battery. ADVANTAGE - The aluminum battery delivers high energy density, high power density, and long cycle life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of aluminum secondary battery which involves providing anode containing aluminum metal or aluminum alloy, providing cathode containing a layer of aligned graphene sheets, and providing porous separator electronically separating anode and cathode and containing electrolyte capable of supporting reversible deposition and dissolution of aluminum at anode and reversible adsorption/desorption and/or intercalation/de-intercalation of ions at the cathode, where layer of aligned graphene sheets is oriented in such a manner that the layer has a graphene edge plane in direct contact with electrolyte and facing or contacting the separator. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the processes for producing intercalated and/or oxidized graphite, subsequently exfoliated graphite worms, separated graphene sheets, and conventional paper, mat, film, and membrane of simply aggregated graphite flakes, graphene sheets, etc.
