Aluminum metal batteries (AMBs) have attracted much attention because of high volumetric capacities (8,040 mAh cm-3) of aluminum metal anode (AMA). However, sluggish ionic transfer on the surface of AMA caused by an oxide passivation layer has substantially impeded the commercialization of AMBs. Therefore, chloroaluminate ionic liquid-based electrolytes (ILEs) with high electrochemical stabilities have attracted considerable attention as an alternative for typical oxygen containing organic electrolyte systems. In this study, 3D porous carbon-based AMA is designed to improve insufficient rate capabilities of the ILE-based electrolyte systems, and electrochemical performances of the AMBs based on the 3D-porous carbon-based AMA were characterized with a graphitic carbon cathode.
