Abstract
Abstract Despite the widespread adoption of Zn anodes for aqueous energy storage, the presence of an inherent passivation layer and the polycrystalline interface of commercial Zn foil consistently lead to non‐uniform electrodeposition, undermining stability and practicality. Herein, the study introduces a chemically polished Zn metal anode (CP‐Zn) fabricated via a simple immersion method. This “chemically polishing” process can effectively remove the interfacial passivation layer (de‐passivation), providing ample active sites for plating/stripping and ensuring the uniformly distributed electric field and Zn 2+ ion flux. Additionally, selective etching during chemical polishing exposes more (002) crystal…
