Abstract (en)
[origin: CA2888484A1] The invention relates to a non-crosslinked, gelled carbonaceous composition and a pyrolysed 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 pyrolysed composition, and to a supercapacitor containing said 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. According to the invention, the composition forms a rheofluidifying physical gel. A pyrolysed carbonaceous composition according to the invention, consisting of 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.
