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 mA h g−1.
