摘要
Abstract The uneven electrodeposition and inferior corrosion resistance are the fundamental obstacles to achieve stable Zn metal anodes. The features of the electrode surface/interface are closely correlated with the properties. Herein, the Zn surface with more exposed (002) Zn planes is modified through a simple acid‐etching approach. The in situ generated zinc compounds form an interface layer with strong adhesion to the Zn electrode, which can enhance the Zn 2+ ion kinetics and regulate the deposition/dissolution behaviors. A variety of acids with functional cations are selected, among which the phosphoric acid etches the Zn with a higher extent of texturing and generates a more compact layer. The obtained zinc phosphate@Zn electrode enables stable cycling and fast kinetics in symmetrical and full Zn metal batteries. This study provides a new example of combined surface and interface modification toward high‐performance aqueous zinc metal anodes.
