Triflate anion chemistry for enhanced four-electron zinc–iodine aqueous batteries

Abstract

I+ hydrolysis, sluggish iodine redox kinetics and the instability of Zn anodes are the primary challenges for aqueous four-electron zinc–iodine batteries (4eZIBs). Herein, the OTf anion chemistry in aqueous electrolyte is essential for developing advanced 4eZIBs. It is elucidated that OTf anions establish weak hydrogen bonds (H bonds) with water to stabilize I+ species while optimizing a water-lean Zn2+ coordination structure to mitigate Zn dendrites and corrosion. Moreover, the interaction of the OTf anions with the iodine species results in an increased equilibrium average intermolecular bond length of the iodine species, facilitating the 4e redox kinetics of iodine with improved reversibility.
