Abstract The practical implementation of aqueous Zn‐ion batteries presents formidable hurdles, including uncontrolled dendrite growth, water‐induced side reactions, suboptimal Zn metal utilization, and intricate anode manufacturing. Here, large‐scale construction a highly oriented ZnO(002) lattice plane on (ZnO(002)@Zn) with thermodynamic inertia kinetic zincophilicity is designed to address such problems. Both theoretical calculations experiment results elucidate that the ZnO(002)@Zn possesses high chemical affinity, hydrogen evolution reaction suppression, dendrite‐free deposition ability due abundant oxygen species in its low mismatch Zn(002). These features synergistically promote ion transport enable homogeneous deposition. Consequently, displays stable prolonged cycling lifespan exceeding 500 h even under larger depth discharge (85.6%) realizes an impressive average Coulombic efficiency 99.7%. Moreover, efficacy also evident V 2 O 5 ‐cathode coin cells pouch not only capacity but exceptional stability.
