Advances in zinc-iodine battery anode materials

A systematic review details recent research progress on cathode materials for zinc-iodine batteries (ZIBs). The review analyzes and discusses strategies to enhance the electrochemical performance of ZIBs, which hold significant potential for large-scale grid energy storage and flexible electronic devices due to their high theoretical capacity, abundant resources, and safety. Key challenges addressed include polyiodide dissolution, the shuttle effect, and the intrinsically poor electrical conductivity of elemental iodine.
