▎ 摘　　要

NOVELTY - The method involves adding mixed oxidizer in concentrated sulfuric acid, which is added with concentrated nitric acid and potassium permanganate at dosage ratio of 35-45 mL:10-15mL:5-7 g. The solution is added on a chemical oxidation strip, which is cleaned and dried to obtain oxidized graphite alkene paper. Dosage ratio of a graphite paper with the mixed oxidant is maintained at a range of 1.5-2.5 g: 45-60 mL. The oxidized graphite alkene paper is placed in an inert gas atmosphere at 80 to 100 degree Celsius to obtain a graphene paper product, where inert gas is nitrogen, helium or argon. USE - Method for preparing a graphene paper that is utilized as electrode material of a capacitor (claimed). ADVANTAGE - The method enables preparing a graphene paper with high stripping degree, excellent conductivity, smooth surface area and super capacitance property using a simple and convenient process in a cost effective manner. The method ensures large scale batch industrial production of the graphene paper, allows the graphene paper to be directly used as super capacitor electrode material, and enables improving application prospect of the graphene paper. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a graphene paper (2) a method for application of a graphene paper. DESCRIPTION OF DRAWING(S) - The drawing shows electrochemical properties of the graphene paper.
