Abstract
A method for producing a porous carbon electrode includes preparing a slurry by mixing a porous, particulate, conductive carbon powder with a solution of a polymer binding agent for the particulate carbon powder in a solvent for the polymer binding agent, forming a precursor electrode by casting the slurry as a layer and subjecting the cast layer to a wet phase inversion to realize porosity in the cast layer, subjecting the thus obtained precursor electrode to a thermal treatment to cause oxidative stabilization, carbonization, dehydrogenation or cyclisation of the polymer binding agent or a combination of two or more of the afore mentioned phenomena by heating the precursor electrode and converting the polymer binding agent into a conductive binding agent binding the particles of the conductive carbon powder together.
