▎ 摘　　要

NOVELTY - Preparing multi-level structure lithium sulfide/carbon composite material comprises mixing lithium source, metal salt solution and graphene oxide solution, drying, obtaining precursor material, annealing the precursor material and the organic compound powder together, and performing autocatalytic reaction and thermal reduction under the condition of the annealing treatment to obtain the multi-level structure lithium sulfide/carbon composite material. USE - The method is useful for preparing multi-level structure lithium sulfide/carbon composite material. ADVANTAGE - The composite material: can stabilize the structure through the composite action of lithium sulfide, reducing graphene oxide and carbon hybrid nanotubes, can alleviate the volume change of lithium sulfide/carbon composite nanomaterials during charging and discharging, and has excellent cycle specific capacity and capacity retention rate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) multi-level structure lithium sulfide/carbon composite material prepared by the above preparation method; and (2) lithium-sulfur battery, comprising multi-level structure lithium sulfide/carbon composite material.
