Single-ion conductive electrolytes can largely eliminate electrode polarization, reduce the proportion of anion migration and inhibit side reactions in batteries. However, they usually suffer from insufficient ion conductivity due to strong interaction between cations cationic receptors. Here we report an ultrafast light-responsive covalent organic frameworks (COF) with sulfonic acid groups modification as acrylamide polymerization initiator. Benefiting reduced electrostatic Zn2+ through solvation effects, as-prepared COF-based hydrogel electrolyte (TCOF-S-Gel) receives up 27.2 mS/cm transference number 0.89. In addition, sufficient hydrogen bonds endow single-ion TCOF-S-Gel have good water retention superb mechanical properties. The assembled Zn||TCOF-S-Gel||MnO2 full zinc-ion battery exhibits high discharge capacity (248 mAh/g at 1C), excellent rate capability (90 10C) superior cycling performance. These enviable results enlist instantaneously photocured be qualified large-scaled flexible high-performance quasi-solid-state
