Lithium sulfur batteries (LSB) have attracted much attention due to their high capacity, but the shuttle of polysulfides during the sulfur reduction reaction (SRR) leads to a decrease in capacity. Metal organic frameworks (MOFs) hybrid carbon matrix materials based on strong conductivity of carbon matrix coupling active sites have been widely used in LSBs. This article introduces the latest research progress on MOFs hybrid carbon based materials as intermediate layers for LSBs. Firstly, the advantages of MOF hybrid carbon based materials as intermediate layers in LSBs were introduced through the shuttle effect during the SRR process. Then, MOFs and carbon matrices were classified into four categories through mixing and growth, including carbon matrices derived from MOFs and carbon matrices derived from MOFs/carbon precursors. This mainly introduces the research progress, existing problems, and development context. Finally, the future design points of MOF hybrid carbon based materials as LSB intermediate layers were discussed, and new requirements were proposed for the design of lithium sulfur intermediate layers. The significance of this review is to contribute to the development of LSB intermediate layers for future practical applications.
