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

摘要

Metal-chalcogen batteries (MCBs) have been considered promising candidatesfor next-generation energy storage because of their low cost, hightheoretical capacity, and environmental friendliness. However, several issues,such as volume changes during charging/discharging, the shuttle effect ofsoluble intermediates, the sluggish reaction kinetics of intermediate conversions,and the uncontrolled dendrite growth of alkali metal anodes, havegreatly impeded the commercialization of MCBs. The introduction of metalorganicframework (MOF)-based materials (pristine MOFs, MOF composites,and MOF derivatives) into different parts of MCBs can effectively overcomethe above issues because these materials possess the advantages of highporosity, low density, large surface area, regular pore channels, tunable poresize, and topological variety. Herein, a detailed overview of recent advancesin MOF-based materials in MCBs, providing comprehensive guidelines forfurther research is presented. MOF-based materials for cathodes and anodesare first summarized, in which the influence of various parameters of pristineMOFs on the properties and the application status of typical compositesand derivatives are presented. MOF-based materials for separators are thenpresented according to different working mechanisms. Next, MOF-basedmaterials for electrolytes are described based on their physical states. Finally,the challenges and outlook for applying MOF-based materials in MCBs arediscussed.
