Abstract

An elaborate Se-deficient Sb2Se3−x/rGO composite is developed by Yongguang Zhang, Jingde Li, Zhongwei Chen, and co-workers in article number 1904876 to establish a reliable “levee” against polysulfide flooding and shuttling, toward high-performance lithium–sulfur batteries. The anion-deficient design in a hierarchical composite is constructed by the thermal shock method, ensuring good intrinsic conductivity, strong polysulfide chemical affinity, and superior catalytic activity, as well as resultant fast and durable sulfur electrochemistry.
