The practical application of Li‐S batteries is still severely restricted by poor cyclic performance caused by the intrinsic polysulfides shuttle effect, which is even more severe under the high‐temperature condition owing to the inevitable increase of polysulfides’ solubility and diffusion rate. Herein, tungsten‐doped vanadium dioxide (W‐VO2) micro‐flowers are employed with first‐order metal‐insulator...
Polysulfide shuttle effect and sluggish sulfur reaction kinetics severely impede the cycling stability and sulfur utilization of lithium‐sulfur (Li‐S) batteries. Modulating d‐band electronic structures of molybdenum disulfide electrocatalysts via p/n doping is promising to boost polysulfide conversion and suppress polysulfide migration in lithium‐sulfur batteries. Herein, p‐type V‐doped MoS2 (V‐MoS...
