Abstract Poly(vinylidene fluoride) (PVDF)‐based solid‐state electrolytes face critical challenges of sluggish ion transport and interfacial instability in lithium metal batteries, exacerbated by crystalline rigidity residual organic solvents. Herein, a composite electrolyte (M 3‐x PVH) integrating oxygen‐vacancy‐rich nanowires into PVDF‐HFP matrix, which establishes the abundant continuous pathways customized ionic microenvironments, is designed. MoO (SNWs) with oxygen vacancies not only promote flexibility polymer chains capture Li⁺ to form for obtaining high conductivity 7.58×10 −4 S cm −1 , but also selectively bind dimethylformamide customize microenvironment accelerating desolvation enhancing stability. Importantly, repel anions via charge repulsion favor anion decomposition, thus forming an inorganic‐rich SEI. Remarkably, Li anode achieves ultra‐long cycling (>8000 h at 0.1 mA −2 ) demonstrates excellent performance paired high‐voltage cathode NCM811. This work pioneers novel strategy designing high‐performance synergistically engineering material dimensionality defect chemistry, unlocking new possibilities next‐generation lithium‐metal batteries.

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.
