Provided is an aluminum secondary battery comprising an anode, a cathode, a porous separator electronically separating the anode and the cathode, and an electrolyte in ionic contact with the anode and the cathode to support reversible deposition and dissolution of aluminum at the anode, wherein the anode contains aluminum metal or an aluminum metal alloy as an anode active material and the cathode comprises a layer of aligned 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. These aligned/oriented graphene sheets are preferably bonded by a binder for enhanced structural integrity and cycling stability. Such an aluminum battery delivers a high energy density, high power density, and long cycle life.
