1. A method for preparing a carbon nanomaterial (CNM)-containing fiber, the method comprising steps of:
(a) receiving a carbanogel product that comprises:
a network of a CNM product that comprises nanocarbon structures, wherein such nanocarbon structures are one or more:
a spherical nanocarbon, a solid nano-onion, a hollow nano-onion, a first nanocarbon of a cylindrical allotrope, a second nanocarbon of a planar allotrope, a third nanocarbon of a helical allotrope, a carbon nanotube (CNT), a nanofiber, graphene, a nano-platelet, a nano-scaffold, a nano-tree, a nano-belt, a nano-flower, a nano-dragon, a nano-rod, a surface modified CNM, a metal coated CNM, and an amorphous nanocarbon, and
an electrolyte that comprises a carbonate;
(b) positioning the received carbanogel product in a vessel;
(c) processing the carbanogel product into a CNM-containing fiber comprising at least a portion of the network of the CNM product dispersed therein, wherein the CNM-containing fiber is larger than individual structures within the nanocarbon structures; and
(d) recovering the CNM-containing fiber.
