Self-supporting electrode with binder-free manufacturing method thereof and supercapacitor comprising the same

摘要

The present invention relates to a self-supporting electrode that does not include a binder and a current collector, a manufacturing method thereof, and a supercapacitor including the self-supporting electrode, wherein the self-supporting electrode includes a three-dimensional graphene structure and a carbon nanotube in a certain content so the self-supporting electrode has high density and high strength and excellent reactivity without binders and current collectors. In addition, the present invention has an advantage of simplifying the manufacturing process by manufacturing the electrode through vacuum filtration of a solution in which a 3D graphene structure and a carbon nanotube are mixed in a solvent.
