▎ 摘  要

NOVELTY - The method, involves forming a solution of graphene oxide and a first solvent. The solution is heated to form a holey graphene oxide. The holey graphene oxide is centrifuged in the solution. The holey graphene oxide is washed in a second solvent. The dispersion is formed of the holey graphene oxide in a third solvent. The acid is added to the dispersion to form a holey graphene oxide framework. USE - Method for composing an electrode with a three-dimensional graphene framework for supercapacitors. ADVANTAGE - Method reduces the mass of the required passive electrode components to allow for a high overall capacity, and reduces the cost of an electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view of a method for composing an electrode.
