In this paper,the fabrication of polarizable electrodes in electric double layer capacitors (EDLCs) based on carbon nanotubes is studied.These talets are prepared by using molded mixtures comprising electrodes.EDLCs with specific capacitance of about 15～25F/g are obtained.Through surveying the major electric performance parameters for the obtained capacitors and comparing them with the ones for conventional activated carbon electrodes,it reveals that carbon nanotube with high accessible surface area and good crytallizing degree has potential advantage in the fabrication of EDLCs.
