▎ 摘  要

NOVELTY - A scattered scale graphene composite contains multidimensional graphenes which are laminated and have sizes of 10 nm to 100 mu m. USE - A scattered scale graphene composite for supercapacitor material. ADVANTAGE - Graphene composite has large specific surface area and reduced contact resistance, and capacitor using the graphene composite has improved electrochemical performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of scattered scale graphene composite which involves preparing graphite oxide by oxidation, preparing graphite oxide aqueous solution, performing ultrasonic treatment to obtain two-dimensional size of graphene oxide aqueous solution, ultrasonically dispersing uniformly to obtain the size of dispersed graphene oxide composite aqueous solution, drying, ultrasonically dispersing prepared graphene aqueous solution with other oxidized graphite alkene aqueous solution to obtain composite oxide graphite alkene-graphene aqueous solution, reducing to obtain the size of dispersed graphene composite, and drying. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional diagram of a scattered scale graphene composite.
