Abstract
(EN) Porous electrolyte membrane comprising a first main surface (21) and a second main surface (22) that are separated by a thickness (23), wherein: - carbon nanotubes, defining pores or through-channels (24) that are open at their two ends (25, 26), have a diameter smaller than or equal to 100 nm, are oriented in the direction of the thickness (23) of the membrane, and are all substantially parallel over the entire thickness (23) of the membrane, connect the first main surface (21) and the second main surface (22); - the carbon nanotubes are separated by a space, and said space between the carbon nanotubes is completely filled with at least one solid material; and, - an electrolyte is confined inside the carbon nanotubes. The invention further relates to a process for producing this membrane and to an electrochemical device, such as a lithium accumulator, comprising said electrolyte membrane.
(FR) Membrane poreuse à électrolyte comprenant une première surface principale (21) et une deuxième surface principale (22) séparées par une épaisseur (23) dans laquelle : - des nanotubes de carbone, définissant des pores ou canaux traversant (24) ouverts à leurs deux extrémités (25,26), d'un diamètre inférieur ou égal à 100 nm, orientés dans le sens de l'épaisseur (23) de la membrane et tous substantiellement parallèles, sur la totalité de l'épaisseur (23) de la membrane, relient la première surface principale (21) et la deuxième surface principale (22); - les nanotubes de carbone sont séparés par un espace, et ledit espace entre les nanotubes de carbone est totalement rempli par au moins un matériau solide; et - un électrolyte est confiné à l'intérieur des nanotubes de carbone. Procédé de préparation de cette membrane. Dispositif électrochimique, tel qu'un accumulateur au lithium comprenant ladite membrane à électrolyte.
