TECHNOLOGY FOCUS - ELECTRONICS - Preferred Components: The electrical or electronic article is a capacitor comprising an electrolyte and a pair of electrodes with a separator disposed between the electrolyte and the electrodes. One or both the electrodes comprise the composition or composite material; or one electrode comprises the composition or the composite material and the other electrode is a conventional capacitor electrode. The other electrode comprises a current collector coated with a composition containing an intrinsically conductive polymer but no carbon.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The carbon has a specific surface area of more than 100 m2/g, as measured according to the BET method. The carbon is graphite, activated carbon black, nanotube or fullerene. The activated carbon black has a specific surface of greater than 750 m2/g.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The carbon has a specific surface area of more than 100 m2/g, as measured according to the BET method. The carbon is graphite, activated carbon black, nanotube or fullerene. The activated carbon black has a specific surface of greater than 750 m2/g.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The composition additionally comprises (wt.%) a liquid dispersion medium (40 - 99.5) (preferably water and/or organic solvent(s)) and other non-evaporable additives (0 - 10). The dispersion medium liquid is evaporable under ambient conditions.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The conductive polymer is a polymer of aniline, thiophene, pyrrole or its substituted derivatives. The average particle size of the conductive polymer is smaller than 500 nm. The weight ratio of the conductive polymer to carbon is 1:50 - 50:1.Preferred Method: The conductive polymer is dispersed in a first liquid and the carbon is dispersed separately in a second liquid. The components are then subsequently mixed. The conductive polymer is dispersed in a liquid and carbon is separately milled in the absence of liquid. The dry milled carbon is subsequently added to the liquid colloidal dispersion of the conductive polymer and dispersed in the dispersion.Preferred Composition: The conductive polymer and carbon components are present in a concentration of 0.5 - 60 wt.%. EXAMPLE - Porous carbonaceous material/conductive polymer composite electrodes were prepared by dispersing pulverized coconut shell active carbon (not yet activated) (18 g) in OKMECON 7301-026-002 (RTM; dispersion of conductive polyaniline in xylene; solid components: 2.2%) (a conductive polymer dispersion) (90.9 g). The resulting mixture was stirred for 60 minutes. To the porous carbonaceous material/conductive polymer slurry, xylene (57.3 g) was further added, and the mixture was stirred for 30 minutes, to prepare a porous carbonaceous material/conductive polymer dispersion. Platinum plates were used for electrodes when using aqueous sulfuric acid solution (1 mol/l) as the electrolytic solution, and aluminum was used for the electrodes when using propylene carbonate as the electrolytic solution. Where platinum was used for the collector plates in the actual electrodes for the capacitor, the surfaces of platinum plates were first scratched with a file, and were then coated with the porous carbonaceous material conductive polymer dispersion. Then, the coated platinum plates were placed in a high temperature tank at 100degreesC for one hour to remove the organic solvent. The electrodes thus formed were subjected to weighing of electrode active substance, and were used directly as the electrodes for the capacitor. Each electrode plate with the electrode active substance in close contact was blanked into circular disks with a diameter of 1 cm, to prepare two electrodes. A glass fiber filter is blanked into circular shape with a diameter of 1.5 cm and used as a separator. Further, an aqueous 1M solution of sulfuric acid was used as an electrolytic solution. Similarly a comparative capacitor cell was prepared by preparing a mixture of electrode material including (wt.%) activated carbon (60), carbon black (30) and tetrafluoroethylene (10) as binder. For film formation, methanol was added to this mixture. An electrode sheet was prepared by using a rolling method. This sheet was dried at 250degreesC at over-wise ambient conditions. Charge discharge test was then carried out in the same manner as the test. The test/comparative capacitor cell showed a charging capacity (F/g) of 250/4.7.
