Abstract The practical implementation of aqueous zinc‐iodine batteries (ZIBs) is hindered by the rampant Zn dendrites growth, parasite corrosion, and polyiodide shuttling. In this work, ionic liquid EMIM[OAc] employed as an all‐round solution to mitigate challenges on both anode iodine cathode side. First, EMIM + embedded lean‐water inner Helmholtz plane (IHP) inert solvation sheath modulated OAc − effectively repels H 2 O molecules away from surface. preferential adsorption metal facilitates uniform nucleation via a steric hindrance effect. Second, can reduce shuttling hindering dissolution forming ‐I 3 dominated phase. These effects holistically enhance cycle life, which manifested || symmetric cells Zn‐I full cells. ZIBs with EAc deliver capacity decay rate merely 0.01 ‰ per after over 18,000 cycles at 4 A g −1 , lower self‐discharge better calendar life than without additive.
