Abstract Aqueous zinc ion batteries provide new solutions for achieving environmentally friendly and safe energy storage devices. Unfortunately, the further application is hampered by growth of dendrites caused uneven deposition, hydrogen evolution other side interfacial reactions at anode. Herein, a multifunctional Bi‐Bi 2 O 3 hybrid artificial interface layer constructed on surface anode using an in situ conversion reaction. Among them, Schottky structure not only significantly accelerates migration Zn 2+ through its built‐in electric field, but also effectively improves barrier (Δ G H* ), thereby suppressing reactions. Moreover, contact formed between metal regulates electronic distribution state optimizes deposition process , ensuring more uniform orderly process. Based synergistic effect dual junctions, symmetric achieve stable cycling 2000 h under conditions 1.0 mA cm −2 mAh . The full cell assembled with α‐MnO as cathode maintains capacity 112.7 g −1 after 1000 cycles 1 A retention rate 84%.
