Abstract Aqueous zinc‐iodine (Zn‐I 2 ) batteries are promising energy storage devices; however, the conventional single‐electron reaction potential and density of iodine cathode inadequate for practical applications. Activation high‐valence reactions has evoked a compelling direction to developing high‐voltage batteries. Herein, ethylene glycol (EG) is proposed as co‐solvent in water‐in‐deep eutectic solvent (WiDES) electrolyte, enabling significant utilization two‐electron‐transfer I + /I 0 − facilitating an additional reversibility Cl /Cl redox reaction. Spectroscopic characterizations calculations analyses reveal that EG integrates into Zn 2+ solvation structure hydrogen‐bond donor, competitively binding O atoms H O, which triggers transition from water‐rich water‐poor clusters , effectively disrupting network. Consequently, aqueous Zn‐I cell achieves exceptional capacity 987 mAh g I2 −1 with 1278 Wh kg marking enhancement ≈300 compared electrolyte devoid EG, enhancing Coulombic efficiency (CE) 68.2% 98.7%. Moreover, pouch exhibits 3.72 cm −2 4.52 mWh exhibiting robust cycling stability. Overall, this work contributes further development high‐capacity
