Summary: In this work, g-C3N4/MoO3 was designed and applied to modify the separator in lithium-sulfur batteries (LSBs). The synergistic adsorption-catalysis effect of g-C3N4/MoO3 can effectively slow down the dissolution of lithium polysulfides (LiPSs), promote the rapid conversion of long-chain LiPSs to Li2S, and improve the electron transportation and deposition/decomposition of Li2S. The g-C3N4/MoO3 modified LSBs showed an initial capacity of 542 mAh g-1 at 4C with a capacity decay rate of 0.0053% per cycle for 700 cycles, demonstrating the potential of this material design strategy for advanced LSBs.

Summary: Lithium-sulfur batteries have potential as new-generation energy storage devices due to their high theoretical energy density and the advantages of sulfur cathodes. However, they face challenges such as low utilization of active materials, volume expansion of the cathode, and loss of active materials. Graphene has been explored as a sulfur host material, but there is still an issue with sulfur escaping from the cathode. Various graphene-based materials with unique structures and chemical compositions have been studied to address this issue. This review summarizes the research progress of three-dimensional graphene, graphene with modified surface chemistry, graphene-based composites, and graphene-based flexible materials as sulfur hosts for lithium-sulfur batteries.
