摘要
Abstract Despite the high theoretical specific capacity of 1675 mAh g −1 , lithium–sulfur batteries (LSBs) are still far away from wide commercialization due to the poor sulfur/Li 2 S electroconductivity and the polysulfides shuttle effect. In order to alleviate the active materials shuttling, separators in LSBs are required to guarantee the fast lithium‐ion transfer as well as the strong polysulfides immobilization. Therefore, various functional materials have been employed to modify the separator to achieve this goal. Among them, metal–organic frameworks (MOFs) with easy morphology design and high ionic or electronic conductivity have been widely investigated. This review summarizes the recent advances of MOF‐based interlayer for LSBs separator functionalization. Original MOFs, MOF derivatives, and MOF composites are included in this discussion. The mechanism of the enhancement of the electrochemical performance of each modified separator is explicated. Furthermore, the prospect of this promising area is provided.
