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.
