Abstract The solar‐driven photorechargeable zinc‐ion batteries have emerged as a promising power solution for smart electronic devices and equipment. However, the subpar cyclic stability of Zn anode remains significant impediment to their practical application. Herein, poly(diethynylbenzene‐1,3,5‐triimine‐2,4,6‐trione) (PDPTT) was designed functional polymer coating Zn. Theoretical calculations demonstrate that PDPTT not only significantly homogenizes electric field distribution on surface, but also promotes ion‐accessible surface With multiple N C=O groups exhibiting strong adsorption energies, this reduces nucleation overpotential Zn, alters diffusion pathway 2+ at interface, decreases corrosion current hydrogen evolution current. Leveraging these advantages, Zn‐PDPTT//Zn‐PDPTT exhibits an exceptionally long cycling time (≥4300 h, 1 mA cm −2 ). Zn‐PDPTT//AC hybrid capacitors can withstand 50,000 cycles 5 A/g. Zn‐PDPTT//NVO battery faster charge storage rate, higher capacity, excellent stability. Coupling with high‐performance perovskite solar cells results in 13.12 % overall conversion efficiency battery, showcasing value advancing upgrading renewable energy utilization.

Rampant dendrite formation and serious adverse parasitic reactions induced by migration of dissolved V/Mn cathode ions on Zn anode have hampered the high performance aqueous zinc-ion batteries (AZIBs). Inspired coordination chemistry between functional groups polymer electrolyte ions, a freestanding layer consisting dopamine-functionalized polypyrrole (DA-PPy) nanowires served as selective ion transport at anode–electrolyte interface to address these two issues, which could simultaneously avoid polarization caused introduction an additional interface. On one hand, DA-PPy displays excellent zinc charge transfer ability, well provides chemical homochanneling for interface, endow with properties guider physical barrier inhibition. other can trap excess transition metal fleeing from cathodes, thus serving barrier, preventing Vx+/Mnx+-passivation surface anode. Consequently, AZIBs based V2O5 MnO2 cathodes involving show great improvement in capacity retention.
