Abstract Aqueous zinc–iodine batteries show immense potential in the electrochemical energy storage field due to their intrinsic safety and cost‐effectiveness. However, rampant dendritic growth continuous side reactions on zinc anode, coupled with shuttling phenomenon of polyiodides, severely affect cyclic life.

Abstract The use of zinc (Zn) metal as an anode in aqueous batteries offers eco‐friendly and cost‐effective energy storage solution.

However, they usually suffer from dendrite growth side reactions, which severely destabilize the electrode/electrolyte interface undermine electrochemical performance. Herein, we report ZnO nanorod-decorated Zn anodes using a facile in situ hydrothermal method. The reactions evolution at anode–electrolyte are systematically investigated. Various characterization techniques suggest that transforms into Zn-ion conductive Zn4SO4(OH)6·4H2O (ZHS·4H2O) interphase, enables uniform deposition suppresses growth. In addition, this passivated interphase can prevent electrolyte direct contact with anode inhibit effectively improving coulombic efficiency (CE) utilization of anodes.
