NOVELTY - Manufacture of polyanthraquinone thioether-graphene-sulfur composite anode material involves dissolving sodium sulfide and elemental sulfur in distilled water to obtain an orange solution, adding nonionic surfactant and concentrated hydrochloric acid, forming a yellow suspension, adding graphene oxide solution, mixing with potassium iodide solution, adding dilute hydrochloric acid, adding N-methyl-2-pyrrolidone, stirring, adding 1,5-dichloroanthraquinone, stirring and adding anhydrous sodium sulfide. USE - Manufacture of polyanthraquinone thioether-graphene-sulfur composite anode material (claimed). ADVANTAGE - The polyanthraquinone thioether-graphene-sulfur composite anode material having excellent flexibility is manufactured. The dissolution of discharge product containing polysulfide is prevented, and volume expansion is mitigated. DETAILED DESCRIPTION - Manufacture of polyanthraquinone thioether-graphene-sulfur composite anode material involves dissolving sodium sulfide and elemental sulfur in distilled water to obtain an orange solution, adding Triton X-100 (RTM: nonionic surfactant) and concentrated hydrochloric acid, forming a yellow suspension, adding graphite oxide to the distilled water, ultrasonically processing to obtain a graphene oxide solution, adding the yellow suspension to obtain graphene oxide solution, adding resulting composite material to a potassium iodide solution, adding dilute hydrochloric acid to obtain a sulfur-graphene composite material, adding the composite material to N-methyl-2-pyrrolidone, stirring, adding 1,5-dichloroanthraquinone, stirring, and adding anhydrous sodium sulfide.
