Mechanistic regulation of multielectron iodine chemistry in aqueous zinc–iodine batteries
Abstract
, aqueous iodine systems can, in principle, access greater electron-storage capacity. However, their practical implementation is hindered by sluggish reaction kinetics, unstable redox intermediates, hydrolysis, and competing side reactions. This review focuses on a central challenge: how high-valence iodine species can be generated, stabilized, and reversibly converted in aqueous electrolytes. We summarize recent advances in solvation regulation, interhalogen mediation, molecular coordination, local microenvironment engineering, and higher-order iodine redox chemistry. We further discuss the mechanistic understanding and materials-design principles emerging from these studies, as well as the remaining challenges that must be overcome in order to develop practical high-energy aqueous iodine batteries.
