Methods for characterizing a nanotube formulation with respect to one or more particular ionic species are disclosed. Within the methods of the present disclosure, this characterization provides control over the surface roughness (or smoothness) and the degree of rafting within a nanotube fabric formed from such a nanotube formulation. In one aspect, the present disclosure provides a nanotube formulation roughness curve (and methods for generating such a curve) that can be used to select a utilizable range of ionic species concentration levels that will provide a nanotube fabric with a desired surface roughness (or smoothness) and degree of rafting. In some aspects of the present disclosure, such a nanotube formulation roughness curve can be used adjust nanotube formulation prior to a nanotube formulation deposition process to provide nanotube fabrics that are relatively smooth with a low degree of rafting.

Embodiments of the present disclosure relate to a process for making a carbanogel buckypaper product. Such carbanogel buckypaper product may be imparted with enhanced properties as compared to other buckypaper products. In some embodiments of the present disclosure, the carbanogel can be generated by an electrolysis process that can transform a carbon-containing gas into a carbon nanomaterial.

A method for carbon nanotube purification, preferably including: providing carbon nanotubes; depositing a mask; and/or selectively removing a portion of the mask; and optionally including removing a subset of the carbon nanotubes and/or removing the remaining mask.

The disclosed method includes a separation step wherein composite particles are transferred to a vicinity of an inlet of a fibrous carbon nanostructure path configured to recover fibrous carbon nanostructures by allowing the fibrous carbon nanostructures to pass therethrough, and a fluid flowing toward the inlet of the path and an external force including a component of a direction opposite to the direction in which the fluid flows are applied to the composite particles to separate the fibrous carbon nanostructures and a particulate ceramic support substrate; and a recovery step wherein the separated fibrous carbon nanostructures are transferred to an interior of the path for recovery by a flow of the fluid, with the separated substrate transferred away from the fibrous carbon nanostructure path for recovery, wherein, in the separation step, the external force applied to the substrate is greater than that applied to the fibrous carbon nanostructures.

A process for purifying raw carbon nanotubes to obtain a content in metallic impurities of between 5 ppm and 200 ppm. The process includes an increase in the bulk density of the raw carbon nanotubes via compacting to produce compacted carbon nanotubes. The process further includes sintering the compacted carbon nanotubes by undergoing thermal treatment under gaseous atmosphere in order to remove at least a portion of the metallic impurities contained in the raw carbon nanotubes, and consequently producing purified carbon nanotubes. These purified carbon nanotubes are directly usable as electronic conductors serving as basis additive to an electrode material without requiring any subsequent purification step. The electrode material can then be used to manufacture an electrode destined to a lithium-ion battery.
