Abstract Aqueous zinc–iodine (Zn‐I 2 ) battery is one of the most promising candidates for large‐scale energy storage due to its cost‐effectiveness, environmental friendliness, and recyclability. Its practical application hindered by challenges including polyiodide “shuttle effect” in cathode anode corrosion. In this study, a zinc pyrrolidone carboxylate bifunctional additive introduced simultaneously tackle issues Zn anode. It revealed that anions decrease concentration preferential coordination between I based on Lewis acid‐base effect, suppressing shuttle effect therefore improving conversion kinetics iodine redox process. Meanwhile, adsorbed inhibit corrosion promote non‐dendritic plating, contributing impressive Coulombic efficiency long‐term cycling stability. As result, Zn‐I full with realizes high specific capacity 211 mAh g −1 (≈100% utilization rate), an ultralong life >30 000 cycles 87% retention. These findings highlight significant potential as transformative aqueous batteries, marking critical advancement field technologies.

Zinc–iodine batteries are one of the most intriguing types that offer high energy density and low toxicity. However, intrinsic conductivity iodine, together with polyiodide solubility in aqueous electrolytes limits development high-areal-capacity zinc–iodine stability, especially at current densities. Herein, we proposed a hydrophobic ionic liquid as zinc-ion battery cathode, which successfully activates iodine redox process by offering 4 orders magnitude higher electrical remarkably lower suppressed shuttle dual-plating cell. By molecular engineering chemical structure liquid, electronic can reach 3.4 × 10–3 S cm–1 Coulombic efficiency 98.2%. The areal capacity achieve 5.04 mAh cm–2 stably operate 3.12 for over 990 h.
