ABSTRACT Aqueous zinc metal batteries (AZMBs) provide a safe and cost‐effective solution to meet the future demand for large‐scale energy storage applications. Stable cycling of Zn anode (ZMA) within wide current range from 0.2 10 mA cm −2 is considered one most critical requirements enable AZMBs. However, studies show that ZMAs may cycle at either high‐ or low‐current densities, but it difficult simultaneously achieve stable this range. Herein, we study current‐dependent coupling interactions among plating, stripping, corrosion ZMAs. We reveal plating/stripping leads unfavorable morphological crystallographic evolution, which results in serious surface rapid failure. In contrast, high‐current can enrich its highly (002) facets form localized high‐concentration electrolyte layers with solvated aggregates, consequently suppresses hydrogen evolution reaction, dendrite formation, corrosion. By understanding these behaviors, develop high‐current‐engineered enables long‐term across range, including record‐breaking 4500 h . This work offers new fundamental insights feasible engineering strategy significantly boost stability
