Abstract
The present invention relates to freestanding carbon nanotube paper comprising purified carbon nanotubes, where the purified carbon nanotubes form the freestanding carbon nanotube paper and carbon microparticles embedded in and/or present on a surface of the carbon nanotube paper. The invention also relates to a lithium ion battery, capacitor, supercapacitor, battery/capacitor, and fuel cell containing the freestanding carbon nanotube paper as an electrode. Also disclosed is a method of making a freestanding carbon nanotube paper. This method involves providing purified carbon nanotubes, contacting the purified carbon nanotubes with an organic solvent under conditions effective to form a dispersion comprising the purified carbon nanotubes. The dispersion is formed into a carbon nanotube paper and carbon microparticles are incorporated with the purified carbon nanotubes.
