▎ 摘  要

NOVELTY - The method involves dispersing graphene oxide in deionized water. Benzene sulfonic acid diazonium salt, sulfanilic crystal acid and sodium hydroxide solution are filled in a beaker. The beaker is cooled at room temperature. Concentrated hydrochloric acid and water are mixed to prepare mixed solution. Starch potassium iodide test paper detection operation is performed. Graphene oxide sulfonation operation is performed. A carbon-coated aluminum foil is formed on a lithium-sulfur battery electrode plate. USE - Sulfonic acid graphene/sulfur battery electrode sheet preparing method. ADVANTAGE - The method enables realizing Sulfonic acid graphene/sulfur battery electrode sheet preparing process in a simple manner with better reproduction quality, better conductivity, certain viscosity and improved volume energy density, cycle property and multiplying power property and avoiding electrolyte diffusion. DESCRIPTION OF DRAWING(S) - The drawing shows a graph illustrating a sulfonic acid graphene/sulfur battery electrode sheet preparing method. '(Drawing includes non-English language text)'
