Abstract： Lithium-sulfur batteries （LSBs） have attracted significant attention due to their high theoretical specific capacity and energy density. However， the severe shuttle effect of lithium polysulfides （LiPSs） and slow redox kinetics limit their commercial application. To address these challenges， a widely spaced MoS2 nanosheets grown on reduced graphene oxide （rGO/IE-MoS2） was designed and used as an intermediate layer coating materials for LSBs to inhibit the shuttle effect of LiPSs. The three-dimensional network structure of rGO and the two-dimensional layered MoS2 nanosheets can enhance the electronic conductivity and Li+ migration rate of the materials， and provide rich catalytically active sites for effective LiPSs adsorption and conversion. The intercalation of carbon expands the interlayer spacing of the MoS2 nanosheets to 103 nm， which effectively reduces the transport barrier for Li + ions. Batteries assembled with rGO/IE-MoS2/CFP as the intermediate layer exhibit excellent rate performance and cycling stability， which have a reversible capacity of 1202 mAh·g -1 at 01C， a capacity fading rate of 0078% per cycle over 500 cycles at 1C， and a high-rate performance of up to 789 mAh·g -1 at 4C. This work provides new insights into the development of catalytic materials for lithium-sulfur batteries.
