Abstract: Lithium sulfur (Li-S) battery is a kind of lithium secondary battery with high theoretical specific capacity (1675 mAh / g) and energy density (2600 Wh / kg), which is considered as one of the most promising secondary battery systems with a high energy storage capability. However, the poor conductivity of sulfur and the shuttle effect of polysulfides hinder the practical application of Li-S batteries. Owing to the unique structures and properties, MOF materials under a series of processing and modification can improve the electrochemical performance and alleviate the shuttle effect. This review focused on the development of MOF materials, summarized the design and preparation of MOF materials, including self-supporting MOF materials, MOF/carbon composites, MOF/(conductive) polymer composites, MOF-derived carbon materials, MOF-derived metal/carbon composites. In addition, the structure-performance relationship of MOF materials is explained in depth, which may enlighten the researchers in related fields and promote the progress of next-generation energy and materials.
