Construction of Electrocatalytic and Heat-Resistant Self-Supporting Electrodes for High-Performance Lithium-Sulfur Batteries.

ABSTRACT: Boosting the utilization efficiency of sulfur electrodes and suppressing the "shuttle effect" of intermediate polysulfides remain the critical challenge for high-performance lithium-sulfur batteries (LSBs). However, most of reported sulfur electrodes are not competent to realize the fast conversion of polysulfides into insoluble lithium sulfides when applied with high sulfur loading, as well as to mitigate the more serious shuttle effect of polysulfides, especially when worked at an elevated temperature. Herein, we reported a unique structural engineering strategy of crafting a unique hierarchical multifunctional electrode architecture constructed by rooting MOF-derived CoS₂/carbon nanoleaf arrays (CoS₂-CNA) into a nitrogen-rich 3D conductive scaffold (CTNF@CoS_2<
