NOVELTY - Preparation of composite material involves grinding sodium sulfide and elemental sulfur, dissolving the mixture in distilled water to form a solution, adding Triton X-100 (RTM: t-octyl phenoxy polyethoxy ethanol) and hydrochloric acid into the solution to form a suspension, adding oxidized graphite and the suspension to form sulfur oxidized graphene composite material, adding obtained material and diluted hydrochloric acid into potassium iodide solution to form sulfur-graphene composite material, and adding water, monomer of thiophene or its derivative and initiator into the material. USE - Preparation of composite material for positive electrode (claimed). ADVANTAGE - The method provides composite material, which inhibits the dissolution of discharge polysulfide product and reduces volume expansion due to the presence of sulfur in the composite material which is covered by flexible graphene and polythiophene. DETAILED DESCRIPTION - Preparation of positive electrode composite material involves grinding sodium sulfide and elemental sulfur in proportion in proportion in an agate motor, dissolving the mixture in distilled water to produce an orange solution, adding Triton X-100 (RTM: t-octyl phenoxy polyethoxy ethanol) into the solution, and adding concentrated hydrochloric acid to produce a yellow suspension, ultrasonically adding oxidized graphite into distilled water to produce oxidized graphene solution, adding the yellow suspension to produce sulfur oxidized graphene composite material, adding obtained material and diluted hydrochloric acid into potassium iodide solution, to form sulfur-graphene composite material, and adding water, monomer of thiophene or its derivative and initiator into sulfur-graphene composite material into to form graphene/polythiophene/sulfur composite material.
