Designing metal-based catalysts is an effective strategy to improve the reaction kinetics by adsorbing and catalyzing the conversion of LiPSs during charge–discharge. Furthermore, considering that metal ions are the main catalytically active sites, further modification of the electronic structure of metal ions and optimization of their adsorption-catalytic effects on LiPSs are the key to promoting the electrochemical properties of Li–S batteries. In this work, Mn, Mo, and Cr are incorporated into CoSe₂ nanosheets to optimize the adsorption–catalysis–desorption process, accelerating the reaction kinetics of Li–S batteries. As a result, the Li–S batteries with Cr-CoSe₂ nanosheet modified separator deliver the best cycle performance and rate performance in comparison to that of the other catalysts. This can be ascribed to the superior catalytic capacity of Cr-CoSe₂ with an optimized electron structure. To be specific, Cr-CoSe₂ possesses the relatively low d band center of Co and proper adsorption strength, in the meanwhile, the shortest Co–S and Li–Se bonds formed between Cr-CoSe₂ and Li₂S₄ can effectively anchor Li₂S₄ and stretch the Li–S bonds longest to break for further conversion.
