| Summary: | 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 contribution.
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 polysulfide
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 inhibiting
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 perspective
for the functional application of MXene based lithium sulfur batteries. |
