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

Abstract Separators are critical components of zinc‐metal batteries (ZMBs). Despite their high ionic conductivity and excellent electrolyte retention, the widely used glass fiber (GF) membranes suffer from poor mechanical stability cannot suppress dendrite growth, leading to rapid battery failure. Contrarily, polymer‐based separators offer superior strength facilitate more homogeneous zinc (Zn) deposition. However, they typically sluggish ion transport kinetics wettability by aqueous electrolytes, resulting in unsatisfactory electrochemical performance. Here a dehydroxylation strategy is proposed overcome above‐mentioned limitations for polyvinyl alcohol (PVA) separators. A dehydroxylated PVA‐based membrane (DHPVA) synthesized at relatively low temperature highly concentrated alkaline solution. Part hydroxyl groups removed and, as result, hydrogen bonding between PVA chains, which deemed responsible kinetics, minimized. At 20 °C, DHPVA reaches 12.5 mS cm −1 , almost 4 times higher than that PVA. Additionally, effectively promotes uniform Zn deposition, significantly extended cycle life reduced polarization, both a/symmetric (Cu/Zn Zn/Zn) full cells (Zn/NaV 3 O 8 ). This study provides new, effective, yet simple approach improve performance ZMBs.
