Abstract
A gelled aqueous polymer composition made from a resin produced by polycondensation of at least: a polyhydroxybenzene R, preferably resorcinol, hexamethylenetetramine HMTA, an anionic polyelectrolyte PA, preferably phytic acid. An aerogel obtained by drying these microparticles, and porous carbon microspheres obtained from the gel microparticles by pyrolysis. A method for producing a polymerised aqueous gel, an aerogel and porous carbon microspheres. Electrodes and electrochemical cell prepared from the porous carbon particles.
