Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as sustainable energy storage systems, yet their practical application is challenged by issues such dendrite growth and hydrogen evolution. A critical factor in enhancing the performance of AZIBs development hydrogel electrolytes (HEs) which offer reduced free water, thereby mitigating side reactions preventing leakage. However, achieving a balance between water maintaining high ionic conductivity challenging. Herein, sulfonate‐modified covalent organic framework (COF‐BSO 3 Zn) designed via facile method intergated it into polyacrylamide (PAM) to form PAM/COF‐BSO Zn (PAM/CBZn) HEs. The COF‐BSO exhibits enhanced aqueous dispersibility significantly improved adsorption capacity for 2+ . PAM/CBZn electrolyte possesses ultrahigh (64.43 mS cm −1 ) excellent transference number (0.84) due ordered porous structure COF‐BSO3 within hydrogel, provides channels efficient transport. Besides, sulfonate groups can regulate solvation structure, contributing uniform deposition inhibiting reactions. Electrochemical tests demonstrate stable cycling over 1800 h with minimal polarization symmetrical cells. This work innovatively highlights new direction tailoring microstructures functional HEs enhance AZIBs, showing great potential toward next‐generation systems.
