▎ 摘  要

NOVELTY - The method involves entering a graphene micro-sheet into a beaker. Dispersing agent is added into the beaker. Ultrasonic process is performed on the beaker for 2 hours. An ultrasonic crushing device is connected with the beaker. The graphene micro-sheet is dispersed in the dispersing agent. Filtering process of a rear micro-porous filter film is carried out. A deionized water leaching process is carried out on a graphene gel thin film. A machinery stirring part is continuously rotated. Low vacuum drying process is performed on the graphene gel thin film to remove volatile liquid. USE - Graphene-containing gel thin film liquid preparation method. ADVANTAGE - The method enables entering the gel thin film into non-volatile liquid so as to avoid collapsing effect of the gel thin film, thus reducing complexity and thickness of gel thin film, and increasing capacity energy density the electrode material. DETAILED DESCRIPTION - The volatility liquid is deionized water, ethanol, acetone, dichloromethane, propionic acid, carbonic acid, dimethyl form amide, dimethyl sulf-oxide or acetonitrile. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of illustrating a graphene-containing gel thin film liquid preparation method.
