Summary: The use of in situ synthesized ultrasmall vanadium nitride nanoparticles dispersed on porous nitrogen-doped graphene as a catalytic interlayer effectively addresses the shuttle effect caused by soluble lithium polysulfides in Li-S batteries. The ultrasmall size of the vanadium nitride particles provides ample triple-phase interfaces for accelerating LiPS conversion and Li2S deposition, resulting in reduced accumulation of LiPS in the electrolyte and inhibition of the shuttle effect. This approach demonstrates high catalytic activity, as evidenced by a significantly reduced activation energy for Li2S4 conversion and a detected decrease in the shuttle effect, thus leading to outstanding cycling performance and high capacity retention in Li-S batteries.

Summary: This study proposes a strategy of integrating sub-nano catalysts into a metal-organic framework (MOF) to address the shuttle effect and sluggish redox kinetics in lithium-sulfur batteries (LSBs). The designed MOF host, MOF-TOC, with sub-nano Ti-O clusters (TOCs), acts as an efficient reaction chamber in the LSBs. The electrochemical tests and calculations demonstrate that MOF-TOC can effectively trap and confine lithium polysulfides (LiPSs) and accelerate the bidirectional redox reactions of sulfur species through the interaction with TOCs. The use of MOF-TOC significantly improves the areal capacity and cycling stability of LSBs at high sulfur loadings and lean electrolytes. This work provides insights into the rational design of catalyst-containing MOF hosts and advances the development of high-performance LSBs.
