Abstract Among optimization strategies for solving the poor ion transport ability and electrolyte/electrode interface compatibility problems of lithium (Li)‐based batteries, halogen elements, such as fluorine (F) iodine (I), have gradually occupied an important position because their superb electronegativity, oxidizability, ionic radius, other properties. The study commences by outlining shared mechanism which F I enhance solid‐state metal batteries' electrochemical performance. In particular, can considerably improve capacity through chemical means intermolecular interactions halogenation reactions. Furthermore, utilization significantly enhances stability via physical strategies, encompassing doping techniques, application surface coatings, fabrication synthetic intermediate layers. Subsequently, characteristics used in Li‐based batteries are elaborated detail, focusing on fact that provide additional energy density anode material but different mechanisms. Additionally, activate dead at negative electrode, act a new carrier. Finally, rational concept synergistic effect is proposed feasibility F–I bihalide solid electrolytes explored.
