Aqueous zinc–iodine (Zn‐I2) battery is one of the most promising candidates for large‐scale energy storage due to its cost‐effectiveness, environmental friendliness, and recyclability. Its practical application is hindered by challenges including polyiodide “shuttle effect” in the cathode and anode...
