The Rise and Development of MOF‐Based Materials for Metal‐Chalcogen Batteries: Current Status, Challenges, and Prospects

Abstract Metal‐chalcogen batteries (MCBs) have been considered promising candidates for next‐generation energy storage because of their low cost, high theoretical capacity, and environmental friendliness. However, several issues, such as volume changes during charging/discharging, the shuttle effect of soluble intermediates, the sluggish reaction kinetics of intermediate conversions, and the uncontrolled dendrite growth of alkali metal anodes, have greatly impeded the commercialization of MCBs. The introduction of metal‐organic framework (MOF)‐based materials (pristine MOFs, MOF composites, and MOF derivatives) into different parts of MCBs can effectively overcome the above issues because these materials possess the advantages of high porosity, low density, large surface area, regular pore channels, tunable pore size, and topological variety. Herein, a detailed overview of recent advances in MOF‐based materials in MCBs, providing comprehensive guidelines for further research is presented. MOF‐based materials for cathodes and anodes are first summarized, in which the influence of various parameters of pristine MOFs on the properties and the application status of typical composites and derivatives are presented. MOF‐based materials for separators are then presented according to different working mechanisms. Next, MOF‐based materials for electrolytes are described based on their physical states. Finally, the challenges and outlook for applying MOF‐based materials in MCBs are discussed.
