Cover Feature: A Multi‐Functional Separator for Li‐S Batteries: WS₂@C Nanoflowers Catalyze the Rapid Recycling of Lithium Polysulfides by Polar Attraction (ChemElectroChem 15/2022)

Abstract

The Cover Feature illustrates the mechanism of the WS2@C‐PP separator enhancing Li‐S battery properties: WS2 nanoflower provides abundant surface‐active sites to adsorb the soluble lithium polysulfides (LiPSs). Being coupled with the high electric conductivity of carbon coating, WS2@C‐PP helps facilitate the charge transfer, catalyzing the conversion reactions from soluble long‐chain to insoluble short‐chain LiPSs on the cathode side. That efficiently improves the utilization of active materials, thus contributing to superior chemical performances than pure PP does. More information can be found in the Research Article by F.
