Engineering MOFs-Derived Nanoarchitectures with Efficient Polysulfides Catalytic Sites for Advanced Li-S Batteries

Lithium-sulfur batteries (LSBs) have received dramatically increased attention because of their manifest advantages. Nevertheless, due to the severe shuttling of lithium polysulfides (LiPSs), sluggish reaction kinetics, and the insulation of sulfur species, the practical application of LSBs is far away. To overcome the abovementioned issues, metal-organic frameworks (MOFs)-derived nanoarchitectures have emerged as one of the most promising cathode materials in designing advanced Li-S batteries. This timely progress report highlights and comments on the most recent advances in designing MOFs-derived nanoarchitectures with diverse electrocatalytic centers as cathode materials for catalyzing the oxidation/reduction reactions of LiPS in LSBs. The molecular/atomic-level electrocatalytic centers, tunable porosities, large specific surface area, controlled components, and versatile structures of MOFs-derived nanoarchitectures are carefully discussed for designing favorable electrocatalysts for LiPS. In particular, the catalytic mechanisms of LiPS based on different types of MOFs-derived materials ranging from single atoms to nanoparticles are systematically summarized. Ultimately, the prospects and challenges of engineering MOFs-derived catalysts for LiPS in LSBs are also suggested. It is believed that this progress report will offer potential guidance and instructive perspectives for designing future state-of-the-art LiPS catalytic materials in LSBs.
