Lithium–sulfur (Li–S) batteries deliver a high theoretical energy density of 2600 Wh kg−1, and hold great promise to serve as a next‐generation high‐energy‐density battery system. Great progress has been achieved in cathode design to deal with the intrinsic problems of sulfur cathodes, including low...
