Abstract:

Lithium-sulfur (Li-S) batteries exhibit great promise for next-generation energy storage due to their high theoretical energy density and low cost. However, their practical application is largely hindered by the shuttle effect. Although previous studies on the adsorption of lithium polysulfides (LiPSs) have achieved significant progress, simple adsorption cannot fundamentally eliminate the shuttle effect. Physical and chemical confinement are useful to anchor LiPSs to some extent, but these are not effective for utilizing the blocked intermediates. Accordingly, accelerating polysulfide redox kinetics is crucial to radically mitigate the shuttle effect and increase sulfur utilization. Herein, recent advances in catalysts for boosting redox kinetics of Li-S batteries are reviewed. We also provide prospects on the design of more efficient catalysts for Li-S batteries.
