▎ 摘　　要

NOVELTY - A composition comprises a graphene macro-assembly-fullerene composite comprising graphene macro-assembly containing a three-dimensional network of graphene sheets crosslinked by covalent carbon bonds, and at least 20 wt.% fullerene compound(s) incorporated into the graphene macro-assembly, based on the weight of the graphene macro-assembly. USE - Composition is used in electrode used for supercapacitor (all claimed) e.g. ultracapacitor or electrical double-layer capacitor. Can also be used in battery electrode, electrical energy storage, micro-batteries, hybrid capacitors, next-generation batteries and hybrid vehicles. ADVANTAGE - The composition improves charge/discharge rates and stability for long period of time of the supercapacitor. The graphene macro-assembly-fullerene composite increases the operational voltage window of the supercapacitor. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for supercapacitor, which comprises an electrode comprising the graphene macro-assembly-fullerene composite and an organic or ionic liquid electrolyte in contact with the electrode.
