Abstract Aqueous zinc‐ion batteries (AZIBs) have emerged as a promising energy storage solution owing to their intrinsic safety, low cost, environmental friendliness, and high theoretical specific capacity. However, practical application is hindered by uncontrollable dendrite growth side reactions at the zinc metal anode. To address these challenges, simple cost‐effective electrodeposition strategy proposed construct quaternary Zn‐Cu‐Sn‐Bi alloy artificial interface layer on foil (ZCSB@Zn) anode of AZIBs. Density functional theory (DFT) calculations in situ optical observation confirm that this dense reduces migration barrier weakens hydrogen adsorption, facilitating uniform deposition while effectively suppressing formation. The symmetric ZCSB@Zn cell exhibits extraordinary cycle stability exceeding 8000 h. Furthermore, assembled ZCSB@Zn//CSB‐MnO 2 full demonstrates capacity 199 mAh g −1 1 A , maintaining even under loading 10 mg cm −2 temperature conditions (50 °C). This study presents scalable for constructing layers anodes, highlighting potential AZIB applications.
