Abstract
High-surface area carbon nanotubes having targeted, or selective, oxidation levels and/or content on the interior and exterior of the tube walls are claimed. Such carbon nanotubes can have little to no inner tube surface oxidation, or differing amounts and/or types of oxidation between the tubes' inner and outer surfaces. Additionally, such high-surface area carbon nanotubes may have greater lengths and diameters, creating useful mechanical, electrical, and thermal properties.
Claims16
A composition for use as a binder material, an electrolyte material or a separator film material of an energy storage or collection device, comprising:
- a plurality of high-surface area carbon nanotubes, wherein at least a portion of the high-surface area carbon nanotubes are open ended;
- wherein the plurality of high-surface area nanotubes are single-wall nanotubes and wherein the BET surface area of the plurality of high-surface area nanotubes is from about 1000 m2/g to about 2000 m2/g according to ASTM D6556-16 and wherein the composition further comprises multi-wall carbon nanotubes wherein the plurality of high-surface area carbon nanotubes have an interior surface oxidized species content which is less than the exterior surface oxidized species content.
