Abstract Application of an aqueous Zn‐ion battery is plagued by a water‐induced hydrogen evolution reaction (HER), resulting in local pH variations and unstable electrode–electrolyte interface (EEI) with uncontrolled Zn plating side reactions. Here, 4‐methyl pyridine N‐oxide (PNO) introduced as redox non‐innocent additive that comprises hydrophilic bipolar N + –O − ion pair coordinating ligand for hydrophobic ─CH 3 group at the para position ring reduces water activity EEI, thereby enhancing stability. The moiety PNO possesses unique functionality efficient push electron donor pull acceptor, thus maintaining desired during charging/discharging.

The integration of water-based electrolytes into zinc-ion batteries encounters challenges due to the limited voltage window water, interfacial side reactions mobile counterions, and growth zinc metal (Zn0) dendrites during charge. In this study, we introduce a nonfluorinated, cation-conducting polyelectrolyte membrane (PEM) designed alleviate these by suppressing reactivities both water counterions. This PEM forms hydrogen bonds with molecules through its proton-accepting chains, thus shifting lowest unoccupied molecular orbital (LUMO) energy from −0.37 −0.14 eV inducing negative shift in onset potential for evolution 110 mV. Additionally, it immobilizes counteranions onto polymer backbones via covalent bonding, hence making Zn2+ transference number nearly unity (0.96). Meanwhile, high modulus establishes solid-state diffusion barrier homogenize flux, leading 3D in-plane compact Zn0 plating within (002) plane. Atomic resolution scanning transmission electron microscopy (STEM) reveals corrosion-free deposition without electrolyte degradation, while operando transition X-ray (TXM) further illustrates real-time dendrite-free process at 5 mA/cm2. Consequently, unique properties water-binding anion-tethering enable enhanced electrochemical performance employing highly fluorinated expensive anions. demonstrates durability 3800 h Zn0–Zn0 symmetric cells lifetime 6000 cycles Zn0–LiV3O8 full cells.
