FIELD: chemistry. n SUBSTANCE: invention refers to the non-cross-linked gel carbon composition, to the pyrolyzed composition correspondingly forming the aqueous polymer gel and its pyrolyzate in the form of porous carbon, to the method for its preparation, to the electrode of porous carbon formed from the pyrolyzed composition, and to the super condenser containing such electrodes. Non-cross-linked gel carbon composition (G2) is the resin composition obtained at least in part from one or more polyhydroxybenzenes R and formaldehyde F, and contains at least one water-soluble cationic polyelectrolyte P. Composition forms the pseudoplastic physical gel. Pyrolyzed carbon composition consists of structurally-integral carbon and is the product resulting from the application, cross-linking, drying and pyrolysis of the non-cross-linked gel composition. Moreover, structurally-integral carbon is mainly microporous and is suitable for the electrode formation for the supercapacitor with the thickness of less than 1 mm. n EFFECT: increase in the viscosity of the gel composition allowing its application with the small thickness and rapid drying is provided. n 16 cl, 1 dwg, 3 tbl |
