▎ 摘　　要

NOVELTY - Producing (M1) a graphene macro-assembly (GMA)-fullerene composite, comprises providing a GMA comprising a three-dimensional network of graphene sheets crosslinked by covalent carbon bonds, and incorporating at least 20 wt.% of at least one fullerene compound into the GMA based on the initial weight of the GMA to obtain the GMA-fullerene composite, where the fullerene compound is covalently bound to the graphene sheets. USE - The methods are useful for producing a GMA-fullerene composites that are useful in manufacturing e.g. supercapacitor electrode (all claimed), battery electrodes, electrical energy storage, micro-batteries, hybrid capacitors, next-generation batteries, hybrid vehicles, and alternative energy storage. ADVANTAGE - The methods provide the: GMA-fullerene composites that exhibit an electrical conductivity of at least 10 S/m, a mesopore volume of at least 0.5 cm3/g, a Brunauer-Emmett-Teller surface area of at least 200 m2/g and a Young's modulus of at least 20 MPa (claimed), where the GMA is free of a polymer coated on the internal surfaces of the GMA; and supercapacitor electrode that exhibits high surface area, good electrical conductivity, and chemical inertness. The methods utilize the fullerene: e.g. 60C that can store up to 6 electrons, or 1 electron/10C as compared with 1 electron/100C for graphitic carbon materials, thus exhibiting a 10-fold increase in electrical storage capacity; and that store charge in a purely electric double-layer capacitance (EDLC) mechanism which is an interfacial phenomenon and does not involve a chemical reaction, hence exhibits rapid charge/discharge rates and increased long-term stability, as the EDLC mechanism does not require protons. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) producing (M2) the GMA-fullerene composite as in the method (M1) as above per se, where the fullerene compound is noncovalently attached to the graphene sheets, and where the incorporating step comprises incubating the GMA in a solution comprising at least one phenylamine functionlized fullerene; (2) a GMA-fullerene composite produced by the method (M1) as above per se; (3) a supercapacitor comprising an electrode comprising the GMA-fullerene composite of either (M1) or (M2) and further comprising an organic or ionic liquid electrolyte in contact with the electrode; and (4) a GMA-fullerene composite produced by the method (M2) as above per se.
