Zinc (Zn) metal, with abundant resources, intrinsic safety, and environmental benignity, presents an attractive prospect as a novel electrode material. However, many substantial challenges remain in realizing the widespread application of aqueous Zn-ion batteries (AZIBs) technologies.

Consequently, these factors contribute diminished lifespan energy efficiency while restricting high-voltage performance. Although numerous reviews have addressed potential separator design mitigate issues some extent, inherent reactivity water remains fundamental source challenges, underscoring necessity for precise regulation active molecules within electrolyte.

Abstract The rampant “top‐growth” dendrites, hydrogen evolution reaction (HER), and zinc (Zn) self‐corrosion severely impede the further development of rechargeable aqueous ion batteries. To address these challenges, a novel double‐layer gradient coating consisting zincophilic Sn inner layer an organic polymer outer (OSA/PAM@Sn) is constructed on surface Zn anode. layer, composed cross‐linked oxidized sodium alginate polyacrylamide (OSA/PAM), not only serves as physical barrier to isolate active water but also accelerates 2+ diffusion by facilitating desolvation process [Zn(H 2 O) 6 ] due its plentiful polar functional groups, thereby effectively suppressing detrimental HER self‐corrosion. Simultaneously, loose can offer abundant nucleation sites induce uniform “bottom‐to‐top” deposition with low overpotential. Benefiting from synergistic effect designed coating, OSA/PAM@Sn‐Zn anode exhibits remarkable reversibility, lifespans over 5000 1200 h at 1 mA cm −2 –1 mAh 5 –5 in symmetric cells, respectively. Additionally, MnO ||OSA/PAM@Sn‐Zn full battery displays improved rate performance cycle stability.
