Ternary Chloride-Free Electrolyte Design for Highly Efficient Aqueous Zinc–Iodine Batteries with Four-Electron Conversion

Abstract

Abstract: A novel class of ternary hybrid aqueous electrolytes composed of betaine, nicotinamide, and zinc sulfate is designed to guarantee the reversible conversion of I–/I0/I+ redox pairs for Zinc-iodine (Zn-I2) batteries to achieve four-electron transfer. Benefiting from the synergistic effect of ternary electrolytes, the Zn-I2 battery exhibits a high specific capacity of 355.5 mAh g–1.
