Abstract
Methods of making single walled carbon nanotubes (SWNTs) including a single step for preparing a homogeneous dispersion of SWNTs in a battery electrode powder. The method may comprise providing a reactor in fluid communication with a mixer, wherein an aerosol containing SWNTs is transmitted from the reactor directly to the mixer containing a battery electrode powder.
Claims10
A method for preparing a dispersion of single walled carbon nanotubes in a battery electrode powder, the method comprising:
- preparing an aerosol containing single walled carbon nanotubes in a reactor;
- and
- transmitting the aerosol directly from the reactor to a mixer containing the battery electrode powder to produce the dispersion,
- wherein the battery electrode powder comprises a primary battery electrode powder material and a secondary material, the secondary material being a surfactant optionally together with a binder,
- wherein a ratio of single walled carbon nanotubes to battery electrode powder is from about 0.01 to 50 wt %;
- and
- wherein the surfactant comprises sodium dodecyl sulfate, wherein the aerosol is continuously transmitted to the mixer as the single walled carbon nanotubes are prodiced in the reactor.
A method for preparing a dispersion of single walled carbon nanotubes in a battery electrode powder, the method comprising:
- preparing an aerosol containing single walled carbon nanotubes in a reactor;
- and
- transmitting the aerosol directly from the reactor to a mixer containing the battery electrode powder to produce the dispersion,
- wherein the battery electrode powder comprises a primary battery electrode powder material and a secondary material, the secondary material being an anionic surfactant optionally together with a binder, and
- wherein a ratio of single walled carbon nanotubes to battery electrode powder is from about 0.01 to 50 wt %, and wherein the aerosol is continuously transmitted to the mixer as the single walled carbon nanotubes are produced in the reactor.
