Abstract
Li-S battery has been regarded as one of the ideal energy storage systems due to its high discharge specific capacity(1 675 m Ah/g). The huge challenge for lithium-sulfur batteries is the utilization of sulfur and lithium metal dendrites. Metal organic frameworks(MOFs) have attracted much attention in lithium-sulfur batteries because of their controllable structure and high specific surface area. This article introduces the research progress of the application of MOFs and its derivative structure materials in lithium-sulfur battery cathodes and separators. The synthesis method
structure and electrochemical performance are summarized accordingly and the current problems
and analysis and outlook the next step of the work direction.
