Abstract Since lithium‐sulfur (Li‐S) batteries have high energy density and environmental friendliness, they garnered a lot of attention as new type storage technology. However, the shuttle effect lithium polysulfides (LiPSs) low utilization sulfur (S) in Li‐S reduce cycle stability efficiency limit their practical application. Therefore, it is urgent to achieve simultaneous immobilization conversion LiPSs utilizing catalysts. Herein, metal–organic framework (MOF)‐derived MoC/WC@NC heterojunction synthesized bidirectional catalyst for high‐performance batteries. Experimental theoretical calculations indicate that expected improve catalytic activity reduction oxidation reactions LiPSs, thereby accelerating kinetics In conclusion, with incorporation novel between cathodes separators batteries, assembled demonstrate excellent rate performance, an initial discharge capacity 1752.1 mAh g −1 at 0.1 C, discharge‐specific 783.2 even 2 C. More significantly, coulombic stayed above 99% 589.1 after 1000 cycles 1 C decay only 0.062% each cycle.
