Lithium-sulfur batteries (LSBs) have attracted extensive research interest due to their high theoretical capacity, low cost, and environmental friendliness. However, the practical application of LSBs is hindered by the severe shuttle effect and slow conversion kinetics of lithium polysulfides (LiPSs). In this manuscript, dual catalytic active sites Ru@Nb₂O₅@NC heterostructure was successfully synthesized through ion exchange and the subsequent high temperature annealing of the ZIF-8 precursor. The obtained Ru@Nb₂O₅@NC heterostructure provides enough channels to accelerate Li⁺ diffusion and the dual active sites of ruthenium (Ru) and niobium oxide (Nb₂O₅) nanocrystals effectively promote the chemical trapping and catalytic conversion of lithium polysulfide (LiPSs). When applied as the modifier of the LSBs separator, the modified Ru@Nb₂O₅@NC separator equipped battery exhibits excellent high initial specific capacity, outstanding rate capability (651.7 mAh/g at 3 C) and excellent cyclic stability with a capacity decline rate of only 0.099% after 500 cycles. It is worth noting that even at high sulfur loading (2.048, 2.432, and 2.944 mg/cm²), the cell still exhibited excellent electrochemical and battery properties. This work provides a feasible strategy for the LSBs separator modification through catalytic conversion and chemisorption of polysulfides.
