▎ 摘　　要

NOVELTY - Processing of graphene oxide involves reducing graphene oxide to obtain reduced graphene oxide. The graphene oxide has pore diameter of 100 nm or less, preferably 20 nm or less. USE - Processing of graphene oxide used as intermediate layer material in anode of lithium-sulfur battery (all claimed). ADVANTAGE - The method enables the manufacture of graphene oxide having improved absorption capacity and preservation ability of the electrolyte, and controls the degree of reduction of reduced graphene oxide. The reduced graphene avoids the deposition of polysulfide ions on surface of anode during charging, reduces the loss of active sulfur and deposition of dead sulfur on the surface of the anode, improves the utilization of sulfur, solves the problems of serious cycle capacity attenuation and poor conductivity of the active material, and improves the electrochemical performance of the lithium-sulfur battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) intermediate layer material, which comprises reduced graphene oxide. The intermediate layer material is in form of network structure. The intermediate layer material has thickness of 10 nm to 200 mu m, preferably 1-30 mu m and pore diameter of 1 nm to 10 mu m, preferably 1-50 nm; (2) anode, which is obtained by loading anode slurry comprising intermediate layer material, onto current collector. The thickness of anode slurry is 3-22 mu m. The loading of anode slurry onto current collector is carried out by wire bar coating method, knife coating method, spin coating method, suction filtration method, spray coating method and layer self-assembly method, preferably wire bar coating method; and (3) lithium-sulfur battery, which comprises the intermediate layer material.
