Efficient catalytic sulfur conversion in aqueous zinc-sulfur batteries mediated by iodide-coupled ether groups
A novel aqueous electrolyte incorporating tetraethylene glycol dimethyl ether (G4) and trace amounts of ZnI<sub>2</sub> (HSG-I) is presented to enhance the sulfur conversion reversibility. G4 improves kinetics, stabilizes the interfaces, and enables uniform zinc deposition. Crucially, G4's ether groups coordinate I<sup>-</sup>, mediating reversible I<sup>-</sup>/I<sub>3</sub><sup>-</sup> transformation to ensure efficient sulfur redox chemistry.
