▎ 摘　　要

NOVELTY - The method involves taking graphene/vanadium pentoxide as raw material. The slurry obtained is uniformly coated in the copper foil. The electrode sheet is punched into a wafer having a diameter of 16 mm. The mass ratio of vanadium pentoxide to graphene is set in preset value. The graphene powder is provided with carbon, nitrogen, and oxygen. The graphene powder is prepared from expanded graphite with an expansion coefficient of 200 to 300 times. USE - Preparation method of graphene/vanadium pentoxide positive electrode sheet used in super capacitor (claimed). ADVANTAGE - The preparation process is simplified. The stable performance is achieved for prepared electrode sheet product. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating the preparation method of graphene/vanadium pentoxide positive electrode sheet used in super capacitor.
