▎ 摘　　要

NOVELTY - The method involves adjusting the catalyst acetic acid for determining the ratio of nickel to carbon source material, by chemical vapor deposition at 450 degrees C. The carbon nanotubes are deposited on the surface of graphene-based gel at 600 degrees C. About 2-20 MPa high pressure is applied to the carbon nanotubes for tableting treatment A core-like carbon nanotube/graphene three-dimensional layered composite electrode material is formed. USE - Preparation method of bud-shaped carbon nanotube/graphene three-dimensional layered composite electrode material for use in super capacitor. ADVANTAGE - The electrode material shows very high capacitive energy and is an excellent electrode material of super capacitor. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of the preparation method of bud-shaped carbon nanotube/graphene three-dimensional layered composite electrode material.
