Orbital Coupling Enables Low-Chloride Electrolyte for Four-Electron Redox in Aqueous Zinc

This research introduces a copper single-atom embedded nitrogen-doped carbon host that stabilizes the electrophilic I+ ion in aqueous zinc electrolytes. By leveraging d-p orbital hybridization and a localized low-concentration chloride environment, the design enhances iodine species adsorption, accelerates redox kinetics, and increases the hydrolysis energy barrier of I+, enabling efficient four-electron redox reactions.
