▎ 摘  要

NOVELTY - The composite has a core, which is made of an activated carbon, where a three-dimensional crumpled graphene shell is coated on a surface of the core in a form for surrounding an outside of the core. The activated carbon is provided with an average particle diameter of 50 nanometers to 500 micrometers. An activated carbon core is provided, where a three-dimensional crumpled graphene shell is provided in a certain weight ratio. USE - Composite for a three-dimensional crumpled graphene structure of a supercapacitor electrode (Claimed) for stably implementing the high electrical conductivity and high specific surface area. ADVANTAGE - The core is made of an activated carbon, where a three-dimensional crumpled graphene shell is coated on a surface of the core in a form for surrounding an outside of the core, and hence ensures improving the power performance of the supercapacitors in an effective manner and reduces the maintenance cost, and also reduces the surface area due to the adsorption of ions, thus secures high electrical conductivity characteristics and achieves the high specific storage capacity due to high specific surface area and the electrical conductivity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for producing a three-dimensional crumpled graphene composite of activated carbon; and (2) a supercapacitor electrode with the carbon nanotubes. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of an activated carbon-three-dimensional crumpled graphene composite. (Drawing includes non-English language text).
