Abstract

Carbonized sucrose-coated eggshell membranes (CSEMs) consisting of natural micropores function well as a polysulfide reservoir in Li/dissolved polysulfide cells. The bottom CSEM current collector encapsulates the active material, while the upper CSEM inhibitor intercepts the migrating polysulfides. This design with CSEM allows the dissolved polysulfides to be localized and the electrochemical reactions within the cathode region to be stabilized, resulting in high discharge capacity, long-term cycle stability, and high sulfur loading.
