▎ 摘　　要

NOVELTY - The diaphragm comprises a battery, a compact modified layer composed of an embedded lithium MOF and a graphene conductive modified layer, where the lithium embedded MOF is particles of lithium ion embedded in the MOF. The load amount ratio of the dense modified layer and the graphene conductivity modified layer in the battery is 4:1-1:4. The thickness of the density modified layer is greater than 1 m. USE - Embedded lithium metal organic framework/graphene composite modified functional diaphragm for lithium-sulfur battery ADVANTAGE - The lithium-embedded MOF/graphene composite modified functional diaphragm has high specific surface area, inhibits the shuttle effect while ensuring the fast transmission of lithium ion in the battery, and improves the capacity and cycle stability of the battery. The graphene conductive modified layer with high conductivity can improve the utilization rate of lithium-sulfonimide (LiPSs). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of lithium-embedded MOF/ graphene composite modified functional membrane. DESCRIPTION OF DRAWING(S) - The drawing shows an SEM image of Li-MOF.
