NOVELTY - Manufacture of spherical nanocarbon fiber assembly involves spraying (S2) a dispersion liquid comprising cellulose nanofibers on a brine liquid and freezing to obtain a frozen component, drying (S3) the frozen component in a vacuum to obtain a dried component, and heating and carbonizing (S4) the dried component in an atmosphere which does not burn the dried component. USE - Manufacture of spherical nanocarbon fiber assembly used for manufacturing carbon nanorods in manufacture of graphene nanoribbons (all claimed). Uses include but are not limited to battery, capacitor, fuel cell, bio-fuel cell, microbial battery, catalyst, solar cell, semiconductor manufacturing process, medical device, beauty instrument, filter, heat-resisting material, fire-resistant material, heat-insulating material, electroconductive ink, electromagnetic shielding material, electromagnetic wave noise absorber, heat-generating component, microwave heat generating component, clothes, carpet, mirror fog prevention material, sensor, touchscreen, etc. ADVANTAGE - The method enables easy, economical and large-scale manufacture of spherical nanocarbon fiber assembly having high specific surface area and conductivity, improved corrosion resistance and stretching property, and suppressed aggregation of aggregation of cellulose nanofibers, without using catalyst support diamond. The fiber assembly maintains three-dimensional network structure. The fiber assembly enables easy, economical and large-scale manufacture of carbon nanorods. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) manufacture of carbon nanorods, which involves pulverizing the fiber assembly; and (2) manufacture of graphene nanoribbons, which involves invading intercalate between graphite layers of the carbon nanorods to obtain an intercalation compound, and peeling each graphite layer of the intercalation compound. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart of the manufacture of the spherical nanocarbon fiber assembly.
