Recent progress in polymer/sulphur composites as cathodes for rechargeable lithium–sulphur batteries

Abstract

Currently, studies with sulphur electrode materials are focused primarily on carbon/sulphur and polymer/sulphur composites. Despite carbon/sulphur composites being a more popular research interest than polymer/sulphur composites, improving the cycle performance of sulphur by using polymers is also a major research focus. Therefore, we review the latest developments for polymer/sulphur composites in Li–S batteries. The various polymer/sulphur composites and their impacts on the electrochemical performance are discussed. Meanwhile, the synthesis approaches toward the various polymer/sulphur composites are also summarised. Finally, the future research directions involving polymer/sulphur composites are addressed.
