NOVELTY - A graphene tape is free-standing and has surface area of at least 200 (preferably at least 400) m2/g; and has an electrical conductivity of at least 100 (preferably at least 1000, especially at least 20000) S/m. USE - As an electrode in a battery (claimed). ADVANTAGE - The tape is free-standing; has a surface area of at least 200 (preferably at least 400) m2/g; has an electrical conductivity of at least 100 (preferably at least 1000, especially at least 20000) S/m. The graphene sheets display little or no signature corresponding to graphite or graphite oxide in their X-ray diffraction pattern. The tape is self-supporting material that may be handled unattached to a substrate or other backing materials and is attached to the other materials including surface, substrate, backing materials, when used in certain applications. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for forming a graphene tape involving: forming a film comprising graphene sheets and at least one polymer binder; and heating the film to decompose the binder.
