TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Compounds: The lithium salt (0.1 - 10 parts by wt.) is lithium perchlorate (LiClO4), lithium tetrafluoroborate (LiBF4), lithium hexafluorophosphate (LiPF6), lithium trifluoromethanesulfonate (LiCF3SO3) or lithium bistrifluoromethanesulfonylamide (LiN(CF3SO2)2). The acid in the precursor mixture is sulfuric acid, nitric acid or phosphoric acid. The supported catalyst comprises the metal catalyst particles (40 - 80 parts by wt.)    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Solvent: The organic solvent (0.01 - 10 parts by wt) is carbonate compound, dimethoxyethane (DME), diethoxyethane, or sulfolane (SUL). The carbon precursor is a sucrose, furfuryl alcohol, divinylbenzene, phenol-formaldehyde, resorcinol-formaldehyde, phenanthrene or anthracene. The acid in the precursor mixture is para-toluene sulfuric acid. The solvent in the precursor mixture is water, acetone, methanol, ethanol, isopropylalcohol, n-propylalcohol, butanol, dimethylacetamide, dimethylformamide, dimethylsulfoxide, N-methyl-2-pyrrolidone, tetrahydrofuran, tetrabutylacetate, n-butylacetate, m-cresol, toluene, ethyleneglycol, gamma-butyrolactone or hexafluoroisopropanol (HFIP). The monomer (0.1 - 10 parts by wt.) is pyrrole, aniline or thiophene.    TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The conductive polymer (0.5 - 8 parts by wt.) is polypyrrole, polyaniline, polythiophene, poly(p-phenylene), or their copolymer with a vinylic monomer (preferably polypyrrole, polyaniline, polythiophene). The average diameter of a mesopore of the mesoporous carbon is 2 - 10 nm, and the mesoporous carbon composite has a specific surface area of 200 - 2000 m2/g and a sheet resistance of 30 - 100 mOmega/cm2 at a pressure of 75.4 kgf/cm2.Preferred Composite: A main peak of Bragg angle 2theta for a CuK-alpha X-ray wavelength of 1.541 Angstrom appears at 1plus minus0.4 degrees and at least one peak appears within 10degrees.Preferred Method: Impregnating of the OMS with the carbon precursor mixture is carried out by impregnating the OMS with a first portion of the carbon precursor mixture, heat-treating the OMS impregnated with the first portion of the carbon precursor mixture at 50 - 250degreesC, and carrying out at least one additional cycle where the OMS is impregnated with at least one additional portion of the carbon precursor and then heat treated. The polymerization is carried out at 0 - 60degreesC in the presence of a polymerization initiator (preferably hydrogen peroxide or ferric chloride) and polymerization catalyst (preferably ammonium sulfate or ferric chloride). The mesoporous silica is removed by dissolving the mesoporous silica with an aqueous hydrogen fluoride solution or an aqueous sodium hydroxide solution. EXAMPLE - Phenanthrene (0.8 g) and para-toluene sulfuric acid (2.4 g) were dissolved in acetone (6 mL) to prepare a homogeneous precursor mixture. The precursor mixture was divided into three parts in a weight ratio of 4:3:2, to prepare solution A, B, and C, respectively. 1 g of SBA-15 (mesoporous silica (OMS) material), was impregnated with solution A. The impregnated SBA-15 was dried at room temperature for 30 minutes, and then dried at 160degreesC for 2 hours. The dried result was impregnated with solution B, and then dried, and treated with the solution C. The dried result was cooled to room temperature, slowly heated to 200degreesC for 1 hour, and maintained for 6 hours. Then, the result was slowly heated to 900degreesC for 4 hours and maintained for 2 hours to form an OMS-carbon composite. The OMS-carbon composite was immersed in 1M pyrrole aqueous solution (50 ml) for 1 hour to allow pyrrole to be absorbed onto the OMS-carbon composite. The pyrrole-adsorbed OMS-carbon composite was obtained though filtering and placed in a 30 wt.% hydrogen peroxide aqueous solution for 1 hour to form polypyrrole. The result was stirred with a mixed solution containing hydrogen fluoride (HF), water and ethanol to remove the SBA-15, and obtain a mesoporous carbon composite coated with polypyrrole. To provide the polypyrrole with electric conductivity, the mesoporous carbon composite was placed in a doping solution of 5 wt.% lithium perchlorate in ethylene carbonate and propylene carbonate at a volume ratio of 1:1 and mixed at room temperature for 48 hours. The polypyrrole-coated mesoporous carbon was filtered, washed, and dried in a vacuum oven at 60degreesC to obtain a doped mesoporous carbon composite. The sheet resistance of the carbon composite before/after doping was 158/53 mOhm/cm2.
