▎ 摘  要

NOVELTY - Composition comprises a combination of a high surface area nanosized graphite and carbon, where the nanosized graphite comprises nanosized graphene nanotubes and nanosized graphene nanoplatelets. USE - The composition is useful in an electrochemical capacitor. ADVANTAGE - The composition improves performance of the electrochemical capacitor in a synergistic manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparing the composition, comprising (i) dispersing graphene in a suitable solvent, (ii) dispersing the carbon in a suitable solvent, (iii) combining and mixing the products of (i) and (ii) to form a slurry, filtering the slurry to provide a sheet form, drying the formed sheet, and calendaring the sheet to a desired thickness and surface finish.
