Abstract Due to the low conductivity of sulfur and the dissolution of polysulfides, the research and application of lithium-sulfur (Li-S) batteries have encountered certain resistance. Increasing conductivity and introducing polarity into the sulfur host can effectively overcome these long-standing problems. Herein, We first prepared Co3W3C@ C@ CNTs / S material and used it in the cathode of lithium-sulfur batteries, The existence of carboxylated CNTs can form a conductive network, accelerate the transmission of electrons and improve the rate performance, and polar Co3W3C can form a strong interaction with polysulfide intermediates, effectively inhibiting its shuttle effect, improving the utilization of sulfur cathode electrodes, and improving the capacity and cycle stability. The Co3W3C@C@CNTs / S electrode material has a capacity of 1,093 mA h g-1 at a 0.1 A g− 1 and 482 mA h g-1 at 5 A g− 1. Even after 500 cycles of 2 A g− 1, the capacity of each cycle is only reduced by 0.08%. The excellent stability of this material can provide a new idea for the future development of lithium-sulfur batteries.
