The lithium-sulfur reaction can contribute to the chemical electrical energy conversion capacity due to the multi-level ion/electron transfer process.However,the appearance of soluble intermediate products prevents efficient electron transfer,making it impossible to achieve stable cycling and capacity contribu-tion.Restricted catalysis provides a solution for inhibiting the shuttle of soluble lithium polysulfides.Herein,MXene aerogel with optimized channel utilization is designed as S host according to the polysul-fide control strategy of localization,adsorption,and catalysis.With the help of the results of oriented channels,the polysulfide conversion process is optimized,providing a comprehensive scheme for inhibit-ing the shuttle effect.Lithium sulfur catalytic batteries have achieved high capacity and stable cycling.This system provides a comprehensive solution for lithium sulfur reaction catalysis and a new perspec-tive for the functional application of MXene based lithium sulfur batteries.
