▎ 摘　　要

NOVELTY - A spacer-modified nano graphene platelet electrode comprises nano graphene platelets or sheets having an average thickness of less than 10 nm, and discrete, non-metallic nano-scaled particles which are disposed between two graphene platelets or sheets as a spacer which prevents re-stacking of graphene platelets or sheets with one another. USE - Spacer-modified nano graphene platelet electrode is used for supercapacitor (claimed) for hybrid electric vehicle e.g. electric car, orbital laser, and complementary metal oxide semiconductor memory backup application. ADVANTAGE - The spacer-modified nano graphene platelet electrode has excellent capacitance, electroconductivity, chemical stability, and reduced density, and is economically manufactured with high productivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for supercapacitor, which comprises two electrodes, a porous separator disposed between the two electrodes, and electrolyte in physical contact with the two electrodes. At least one of the two electrodes comprises spacer-modified nano graphene platelet electrode.
