Lithium–sulfur (Li–S) batteries exhibit great potential as a next-generation rechargeable battery system due to their high energy density, natural abundance, and nontoxicity. Nevertheless, the insulated nature of S and Li2S and the electrochemical instability of intermediate lithium polysulfides (Li...
