Abstract: The invention relates to a noncrosslinked gelled carbonaceous composition and a pyrolyzed composition respectively forming an aqueous polymer gel and the pyrolysate thereof in the form of porous carbon. The invention also relates to the production method thereof, to a porous carbon electrode formed by the pyrolyzed composition, and to a supercapacitor containing said electrodes. The gelled, noncrosslinked composition (G2) is based on a resin created at least partly from polyhydroxybenzene(s) R and formaldehyde(s) F and comprises at least one hydrosoluble cationic polyelectrolyte P. According to the invention, the composition forms a rheofluidifying physical gel. A pyrolyzed carbonaceous composition according to the invention, consisting of a carbon monolith, is the product of coating, crosslinking, drying and pyrolysis of the non-crosslinked gelled composition, the carbon monolith being predominantly microporous and able to form a supercapacitor electrode having a thickness of less than 1 mm.

Abstract: The invention relates to a gelled carbon-based composition forming an organic polymeric monolithic gel which is suitable for forming an aerogel by drying, to uses and to a process for preparing this carbon-based composition. The invention applies especially to the production of such gels having a very low density and a very low heat conductivity, a very high specific surface area and a satisfactory compression strength, for their use as thermal superinsulators or as carbon-based electrode precursors of supercondensers.A composition according to the invention comprises a resin at least partly derived from polyhydroxybenzenes H and from formaldehyde(s) F, said polyhydroxybenzenes comprising at least one unsubstituted polyhydroxybenzene R′ and at least one polyhydroxybenzene substituted with one or two alkyl groups.This composition is such that said polyhydroxybenzenes comprise several said unsubstituted polyhydroxybenzenes R and R′ and in that the composition comprises a water-soluble cationic polyelectrolyte P.

Also provided is a production method thereof, to a porous carbon electrode formed by the pyrolysed composition, and to a supercapacitor containing the electrodes. The gelled, non-crosslinked composition (G2) is based on a resin created at least partly from polyhydroxybenzene(s) R and formaldehyde(s) F and comprises at least one hydrosoluble cationic polyelectrolyte P. The composition forms a rheofluidifying physical gel. A pyrolysed carbonaceous composition having a carbon monolith, is the product of coating, crosslinking, drying then pyrolysis of the non-crosslinked gelled composition, the carbon monolith being predominantly microporous and able to form a supercapacitor electrode having a thickness of less than 1 mm.
