▎ 摘　　要

NOVELTY - The electrode has a carbon nanotube formed by a Three Dimensional (3D) graphene structure, where the 3D graphene structure is 1.0 cm based on the electrode. The carbon nanotube is provided with ten units to 20 units based on weight of the three-dimensional graphene structure. The ratio of carbon to oxygen (C/0) is 25 or more based on the three-dimensional graphene structure. The strength of the electrode is 10 MPa to 100 MPa and the density of the electrode is 0.4 to 1 g/cc. USE - Binder-free self-supporting electrode for a super capacitor (Claimed). ADVANTAGE - The electrode has high strength of the electrode without a binder and a current collector, excellent reactivity, high safety performance and simple structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a binder-free self-supporting electrode manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a transmission electron microscope image of a graphene structure.
