Abstract Zn foil pretreatment is a direct route to alleviating anode instability and maintaining high energy performance in metal batteries. Unfortunately, prevailing methods for achieving an ideal surface texture do not enable durable operation under large depth of discharge, thus impairing the utilization ratio. etching more feasible way control texture, but this approach remains relatively unexplored. In study, general strategy reported engraving aprotic media realize efficient terms stability. These tests are performed using high‐valence ions (especially Mo 5+ ) environment as key etchant render homogenously‐distributed, 3D porous architecture on surface.
