The Frontiers of Aqueous Zinc–Iodine Batteries: A Comprehensive Review on Mechanisms, Optimization, and Industrial Prospects

Abstract Zinc–iodine batteries, grounded in halogen‐powered static conversion mechanisms, are experiencing significant development. However, clarity regarding their industrialization pathway remains elusive. This review delves into the energy storage mechanism of zinc–iodine batteries, encompassing not only the conventional low‐valence transformation mechanism but also spotlighting emerging high‐valence transformation mechanisms. Simultaneously, several optimization routes are proposed from the perspective of battery industrialization, mainly covering the optimization direction of cathode and anode materials, including efficient restraints of iodine effect behavior, promotion of iodine conversion reaction, and…
