Research interest in aqueous rechargeable batteries (ARBs) has increased in recent years, because ARBs have many advantages such as high kinetic performances, environmental benignity, and nonflammable aqueous electrolytes. Among of ARBs, one of the most promising candidates is aqueous zinc batteries (AZBs) owing to high theoretical capacity, low redox potential, and excellent chemical stability. However, the AZBs suffers from poor electrochemical performances of zinc metal anode (ZMA) such as low CE originating from side reactions and dendritic metal growth during cycling process. Although mildly acidic aqueous electrolytes are partly effective for the issues, the ZMA still suffers from the poor electrochemical performances. In this study, we propose a surface-modified carbon-based electrode material to guide a selective zinc metal deposition with no side reaction. Hence, high-performance AZBs were achieved by introducing the surface-modified carbon-based electrode materials for ZMA. |
