The “shuttle effect” and slow conversion kinetics of lithium polysulfides (LiPSs) are stumbling block for high‐energy‐density lithium–sulfur batteries (LSBs), which can be effectively evaded by advanced catalytic materials. Transition metal borides possess binary LiPSs interactions sites, aggrandizing the density of chemical anchoring sites. Herein, a novel core–shelled heterostructure consisting...
The improvement of lithium–sulfur batteries is still impeded by notorious shuttling effect and sluggish kinetics on the S cathode, and rampant Li dendrite formation on the Li anode makes it worse. Herein, a type of single‐atom dispersed Mo on nitrogen‐doped graphene (Mo/NG) with a distinctive Mo‐N2O2‐C coordination structure first serving as a multifunctional material is designed by a structure‐oriented...
The practical application of lithium–sulfur batteries is still limited by the lithium polysulfides (LiPSs) shuttling effect on the S cathode and uncontrollable Li‐dendrite growth on the Li anode. Herein, elaborately designed WSe2 flakelets immobilized on N‐doped graphene (WSe2/NG) with abundant active sites are employed to be a dual‐functional host for satisfying both the S cathode and Li anode synchronously...

Lithium–sulfur battery (LSB) is regarded as a preferential option for next‐generation energy‐storage system, but the lithium polysulfides (LiPSs) shuttling effect and the uncontrollable growth of dendritic Li in the anode impede its commercial viability. To address both of the issues simultaneously, a well‐designed hybrid of MgO ultrafine nanocrystals dispersed on graphene‐supported carbon nanosheets...
