Flexible zinc-ion batteries (ZIBs) with high capacity and long cycle stability are essential for wearable electronic devices. Hydrogel electrolytes have been developed to provide ion-transfer channels while maintaining the integrity of ZIBs under mechanical strain. However, hydrogel matrices typically swollen aqueous salt solutions increase ionic conductivity, which can hinder intimate contact electrodes reduce properties. To address this, a single-Zn-ion-conducting electrolyte (SIHE) is by integrating polyacrylamide network pseudo-polyrotaxane structure. The SIHE exhibits Zn2+ transference number 0.923 conductivity 22.4 mS cm-1 at room temperature.

It has strong zincphilicity suppression ability due significant interaction electronegative nucleophilic carbonyl oxygen, favoring transport homogenizing effectively. On other side, bond formed by proton acceptor oxygen atom in ZCO regulates Zn-ion desolvation process at interfaces, thus bounding water activity then mitigating water-induced parasitic reactions. Consequently, Zn@ZCO exhibits extended cycling lifespan 5000 h (>208 days) dendrite-free surface negligible by-products.
