Aqueous Zn-ion batteries (AZIBs) attract intensive attention owing to their environmental friendliness, cost-effectiveness, innate safety, and high specific capacity. However, the practical applications of AZIBs are hindered by several adverse phenomena, including corrosion, Zn dendrites, hydrogen evolution. Herein, a anode decorated with 3D porous-structured Na3 V2 (PO4)3 (NVP@Zn) is obtained, where NVP reconstruct electrolyte/anode interface. The resulting NVP@Zn can provide large quantity fast stable channels, facilitating enhanced ion deposition kinetics regulating ions transport process through confinement effect. NASICON-type protective layer promote desolvation due its nanopore structure, thus effectively avoiding side reactions. Theoretical calculations indicate that electrode has higher binding energy migration barrier, which demonstrates enhance prevent unfettered 2D diffusion ions. Therefore, results show NVP@Zn/MnO2 full cell maintain discharge capacity 168 mAh g-1 high-capacity retention rate 74.6% after cycling. extraordinary obtained this strategy have confirmed promising in high-performance AZIBs.
