Boosting Reversible Four-Electron Redox in Aqueous Zn-Iodine Batteries with Two Halogen Ionic Additives and a N, F Codoped Carbon Cathode

ACS Applied Energy Materials, Journal Year: 2025, Volume and Issue: 8(1), P. 601 - 610

Published: Jan. 1, 2025

Recent interest has focused on aqueous zinc–iodine batteries (AZIBs), yet their practical application is hampered by limited capacity and energy density. To overcome these limitations, we report herein AZIBs with improved electrochemical performance incorporating two halogen-containing ionic additives (0.1 M ZnI2 0.1 ZnBr2) into the ZnSO4 electrolyte. Importantly, unlike previously reported approaches, nitrogen fluorine codoped porous carbon (N/F-PC) can be directly utilized as cathode material for without need preloading iodine. This allows full utilization of its rich structure, thereby promoting four-electron redox reaction (based iodine molecule) facilitating conversion between I– I+. Besides, bromide (Br–) introduced to activate species stabilizing I+ through formation interhalogen bonds. The resulting display distinct discharge plateaus at 1.55 1.15 V, corresponding reversible reactions among I–/I0/I+. In contrast, control electrolyte ZnBr2 additive exhibits only a single plateau V. Consequently, N/F-PC-based demonstrate large specific 452.6 mAh g–1 huge density 584.1 Wh kg–1, significantly outperforming conventional Zn-iodine based I–/I0. strategy presented in this study may pave way development high-energy-density storage devices.
