1. A method of making a self-supportive electrode material, the method comprising:
providing an aerosolized plurality of carbon nanotubes in a carbon nanotube synthesis reactor;
transporting the aerosolized plurality of carbon nanotubes directly from the carbon nanotube synthesis reactor to a mixing chamber;
providing an aerosol mixture by contacting the aerosolized plurality of carbon nanotubes in the mixing chamber with an aerosolized electrode active material from a first chamber and an aerosolized additive from a second chamber;
creating a vortex of the aerosol mixture in the mixing chamber to provide a substantially homogenous aerosol mixture comprising the carbon nanotubes, the electrode active material, and the additive; and
depositing the carbon nanotubes, the electrode active material, and the additive directly on a porous substrate to provide a self-supportive electrode material.
