NOVELTY - Preparation of graphene paper comprises taking graphene oxide paper, carrying out thermal reduction under vacuum at 150-200 degrees C for 1-2 hours, placing in tubular furnace, and heating under inert gas protection and reducing gas atmosphere. USE - Method for preparing graphene paper used as current collector (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation graphite oxide paper comprising taking graphite, adding concentrated sulfuric acid and potassium permanganate, incubating at 0-10 degrees C for 2-4 hours, stirring at room temperature for 12-24 hours under ice bath condition, slowly adding deionized water, adding hydrogen peroxide to remove potassium permanganate, filtering, washing using dilute hydrochloric acid and drying.
