Lithium sulfur batteries (LSBs) have attracted tremendous attention owing to their high theoretical specific capacity and specific energy. However, their practical applications are hindered by poor cyclic life, mainly caused by polysulfide shuttling. The development of advanced materials to mitigate the polysulfide shuttling effect is urgently demanded. Metal-organic frameworks (MOFs) have been exploited as multifunctional materials for the decoration of separators owing to their high surface area, structural diversity, tunable pore size, and easy tailor ability. In this review, we aim to present the state-of-the-art MOF-based separators for LSBs. Particular attention is paid to the rational design (pore aperture, metal node, functionality, and dimension) of MOFs with enhanced ability for anchoring polysulfides and facilitating Li transportation. Finally, the challenges and perspectives are provided regarding to the future design MOF-based separators for high-performance LSBs.
锂硫电池（LSBs）因其高理论比容量和比能量而备受关注。然而，其实际应用受到循环寿命较差的阻碍，这主要是由多硫化物穿梭效应引起的。迫切需要开发先进材料来减轻多硫化物穿梭效应。金属有机框架（MOFs）因其高比表面积、结构多样性、可调孔径和易于定制的能力，已被用作装饰隔膜的多功能材料。在这篇综述中，我们旨在介绍用于锂硫电池的基于MOF的隔膜的最新进展。特别关注具有增强固定多硫化物和促进锂传输能力的MOFs的合理设计（孔径、金属节点、功能和尺寸）。最后，针对未来设计用于高性能锂硫电池的基于MOF的隔膜提出了挑战和展望。
