▎ 摘 要
NOVELTY - Pores are formed on the surface of a graphene sheet by processing the graphene sheet with hydrofluoric acid. Then, a graphene composite comprising sulfur particles is synthesized by growing the sulfur particles on formed pores, to obtain electrode of secondary battery. USE - Manufacture of electrode for forming secondary battery e.g. lithium-sulfur secondary battery (all claimed). ADVANTAGE - The lithium-sulfur secondary battery obtained using electrode high capacity and reduced side effects, and effectively inhibits polysufide elution caused by solution reactions in battery charge and discharge regulator. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of secondary battery, which involves forming graphene composite electrode-containing lithium-sulfur secondary battery. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of secondary battery. Anode electrode (100) Anode collector (120) Cathode electrode (200) Cathode collector (220) Separation film (300)
