Boosting Polysulfide Redox Kinetics by Temperature‐Induced Metal‐Insulator Transition Effect of Tungsten‐Doped Vanadium Dioxide for High‐Temperature Lithium‐Sulfur Batteries

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-VO
