A major challenge hindering the large-scale commercialization of lithium-sulfur (Li-S) batteries lies in the sluggish redox kinetics of polysulfides. This study proposes a microstructure design strategy that involves loading densely dispersed CoP nanoparticles onto the surface of MXene layered materials. MXene not only provides a large specific surface area to support a high density of active CoP nanoparticles

but also offers excellent conductivity and abundant surface functional groups that serve as additional reactive sites. Furthermore

the densely dispersed CoP nanoparticles not only function as the major active sites

but also effectively prevent the self-stacking of MXene sheets

thereby enhancing the microstructural stability. Compared to the coin cells assembled with individual CoP or MXene materials

the battery made by CoP-MXene composite cathode exhibits significantly enhanced performance

maintaining a high discharge specific capacity of 632 mA·h·g
