NOVELTY - Preparing a bismuth compound sulfur composite electrode material, involves mixing the graphene oxide solution with a surfactant, and ultrasonically preparing a suspension solution of graphene oxide, adding a soluble inorganic salt of cerium to the graphene oxide suspension solution, adding an alkali solution or an acid solution to an oil bath, and drying to obtain a cerium compound-graphene oxide composite material. The graphene oxide composite material and the sulfur powder are sufficiently ground to obtain a mixed powder, and the mixed powder is subjected to heat treatment to obtain a bismuth compound sulfur composite electrode material. USE - Preparing a bismuth compound sulfur composite electrode material. ADVANTAGE - The preparation method of a bismuth compound sulfur composite electrode material, solves the technical problem that the existing lithium-sulfur battery material has poor uniformity, the polysulfide is easily dissolved and the carbon structure is required to be high.
