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.
