TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The melt or the solution of the carbon fiber-precursor polymer contains a graphitization catalyst. The graphitization catalyst is particles of a metal selected from a transition metal and/or non-transition metal; or a compound of the metal which can form the corresponding metal particles during the carbonization step. The transition metal is Pt, Ru, Cu, Fe, Ni, Co, Pd, W, Ir, Rh, Sr, Ce, Pr, Nd, Sm, and/or Re; the non-transition metal is Mg, B, and/or Al; and the metal compound is selected from CuCl2, CoCl2, OsCl3, CrCl2, VCl3, TaCl2, TiCl4, (NH3)6RuCl3, ZrCl4, HfCl4, MnCl2, ZnCl2, FeCl3, NiCl2, PdCl2, MgCl2, Pd(NO3)2, (NH3)4Pt(NO3)2, Fe(NO3)3, Ni(NO3)2, Mg(NO3)2 and organometallic compound containing Fe, Pd, and/or Ni.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The binder is selected from polyurethane and polyurethane copolymers comprising polyetherurethane; cellulose derivatives such as cellulose acetate, cellulose acetate butylate and cellulose acetate propionate; polymethylmethacrylate (PMMA); polymethylacrylate (PMA); polyacryl copolymers; polyvinylacetate and polyvinylacetate copolymers; polyvinylalcohol (PVA); polyperfurylalcohol (PPFA); polystyrene and polystyrene copolymers; polyethyleneoxide (PEO); polypropyleneoxide (PPO) and polyethyleneoxide copolymers; polypropyleneoxide copolymers; polycarbonate (PC), polyvinylchloride (PVC), polycaprolactone, polyvinylpyrrolidone (PVP), polyvinylfluoride, polyvinylidenefluoride and their copolymers; and polyamide. The carbon fiber-precursor polymer is: 1) petroleum pitch or coal pitch, 2) a polyacrylonitrile or polyacrylonitrile copolymer, 3) cellulose or a cellulose derivative, or 4) a halogenated polymer. The halogenated polymer is selected from: homopolymers and copolymers of fluoropolymers comprising poly(vinylidene fluoride), poly(vinylidenefluoride-co-hexafluoropropylene), poly(vinylidenefluoride-co-tetrafluoroethylene), poly(vinylidenefluoride-co-trifluoroethylene) and perfluoropolymers; and/or homopolymers and copolymers of halogenated monomers comprising polyvinyl chloride, poly(vinylidene chloride), poly(vinylidenechloride-co-vinylchloride) and/or saran polymers. The melt or the solution of the carbon fiber-precursor polymer further comprises carbon black or carbon nanotubes dispersed uniformly. Preferred Method: The mixture used in step (b) further comprises a conducting material. The carbon substrate of step (b) is formed using a doctor-blade or electrospray method. The metal oxide thin layer of step (c) is deposited on the carbon substrate by a constant current or cyclic voltammetry method. The method further comprises the step of heat-treating the metal oxide thin layer after step (c). The step (a) further comprises heat-treating the spun fibers obtained after electro-spinning at less than or equal to 300 degrees C before the carbonizing step; and activating the ultrafine carbon fibers under an oxidative environment. The carbonization in step (a) is conducted in the presence of a 1-10C hydrocarbon gas. EXAMPLE - A graphitical ultrafine carbon fiber (0.85 g) having a specific surface area of 430 m2/g was mixed with Super-P (RTM: conducting material) (0.05 g). Added to the resulting mixture was the polymer solution containing polyvinylidenefluoride-hexafluoropropylene (PVdF-HFP) (0.1 g) dissolved in N-methyl-2-pyrrolidone (NMP) (5 ml). The resulting mixture was coated on a titanium collector using the doctor-blade method to obtain a carbon substrate. The deposition of a ruthenium oxide thin layer on the carbon substrate was carried out by cyclic voltammetry method using an aqueous solution of ruthenium chloride. The graphitical carbon fiber substrate was soaked in 0.05M ruthenium chloride, and the deposition was carried out by sweeping 10 times at a voltage of 0.2 to 1.4V relative to silver/silver chloride electrode at a sweep rate of 300 mV/seconds. The deposited electrode was heat-treated at 175 degrees C for 30 minutes. The specific capacitance of the electrode depending on the change of the sweep rate was measured. The result showed that the specific capacitance of the electrode formed was maintained about 77% in spite of the change of the sweep rate from 10-500 mV/sec.
