Suppressing rapid capacity decay caused by the shuttle effect of dissolved lithium polysulfides between two electrodes is crucial to the realization of a practical lithium–sulfur (Li–S) batteries.
An oxidized multiwall carbon nanotube (o-MWCNT) coating (0.4 mg cm−2) for improving the electrochemical performance of lithium–sulfur battery with sulfur loading of 5.0 mg cm−2 has been presented.
