Electric double-layer capacitors using carbon nanotube electrodes and organic electrolyte

Porous tablets of carbon nanotubes were used as polarizable electrodes in electric double-layer capacitors (EDLC). The specific surface area and pore specific volume of the carbon nanotube materials were measured. An energy density of about 20 W h/kg of EDLC using these polarizable electrodes were obtained on a single cell device with an organic liquid solvent as electrolyte. (C) 2001 Elsevier Science B.V.
