Owing to the high volumetric capacity (8,060 mA h cm-3) and abundant element metal on earth, aluminum metal anode (AMA) has attracted much attention as an active anode material for next-generation high-energy-density batteries. However, AMA has the intrinsic issue, galvanic corrosion induced by Lewis acidic ionic liquid electrolyte (ILE). A corrosion reaction occurs at the surface of AMA, increasing the amount of aluminum oxide and modifying the morphology of the surface. Also, AMA attacked by ILE causes additional side reactions, resulting in a loss of coulombic efficiency and hindering the overall electrochemical performance. In this study, 3D-nanostructed electrode material with outstanding chemical properties was designed to guide homogeneous aluminum metal nucleation and growth and to suppress corrosion in ILE, and its electrochemical performances for AMA was investigated.
