▎ 摘　　要

NOVELTY - Graphene/functionalized metal-organic framework material composite intercalation layer comprises graphene and a functionalized metal-organic framework material, where the functionalized metal-organic framework material is distributed on the surface of the graphene, the ratio of graphene and functionalized metal-organic framework material is 5-1:1, and the functionalized metal-organic framework material is UIO-66, UIO-66-COOH, UIO-66-2OH, UiO-66-2NH2. USE - Graphene/functionalized metal-organic framework material composite intercalation layer used in a lithium-sulfur battery (claimed). ADVANTAGE - The graphene/functionalized metal-organic framework material composite intercalation layer has high capacity and slow attenuation at high rate, promotes electrolyte absorption and lithium ion diffusion, effectively reduces the interface impedance, inhibits the shuttle effect of polysulfide, reduces the loss of active substance, exhibits excellent cycle stability and multiplying power performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a graphene/functionalized metal-organic framework material composite intercalation, which involves mixing graphene and functionalized metal-organic framework material uniformly to obtain graphene/functionalized metal-organic framework material dispersion and depositing graphene/functionalized metal-organic framework material on the non-polar separator of a lithium-sulfur battery, and drying to obtain product.
