Title (EN) PROCESS FOR PRODUCING A POROUS CARBON ELECTRODE.
(FR) PROCÉDÉ DE FABRICATION D'UNE ÉLECTRODE EN CARBONE POREUX
Abstract:
(EN) The present invention relates to a method for producing a porous carbon electrode, which method comprises the steps of 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, wherein the polymer binding agent is a polymer material selected from the group of a carbonisable polymer material, a polymer material which may undergo cyclization, oxidative stabilization or dehydrogenation, or a mixture of two or more of the afore-mentioned polymer binding agents.
(FR) La présente invention concerne un procédé de production d'une électrode en carbone poreux, ledit procédé comprenant les étapes suivantes : préparation d'une bouillie par mélange d'une poudre de carbone conducteur particulaire poreux avec une solution d'un agent liant polymère pour la poudre de carbone particulaire dans un solvant pour l'agent liant polymère, formation d'une électrode précurseur par moulage de la bouillie sous forme de couche et soumission de la couche moulée à une inversion de phase humide pour réaliser une porosité dans la couche moulée, soumission de l'électrode précurseur ainsi obtenue à un traitement thermique afin de provoquer la stabilisation oxydative, la carbonisation, la déshydrogénation ou la cyclisation de l'agent liant polymère, ou une combinaison d'au moins deux des phénomènes susmentionnés, par chauffage de l'électrode précurseur et conversion de l'agent liant polymère en un liant conducteur liant ensemble les particules de la poudre de carbone conductrice. L'agent liant polymère est un matériau polymère choisi dans le groupe comprenant un matériau polymère pouvant être carbonisé, un matériau polymère qui peut subir une cyclisation, une stabilisation oxydative ou une déshydrogénation, ou un mélange d'au moins deux des agents de liaison polymères susmentionnés.
