Patent

CA 2653114

The invention relates to an electrode comprising (a) an electron collector containing one or more transition metals from the groups 4 to 12 of the Periodic Classification of the Elements, and (b) a material that is electrochemically active, present on the surface of the electron collector in the form of a nano-structured conversion layer containing nano-particles or agglomerates of said nano-particles, wherein the nano-particles have a mean diameter of between 1 and 1000 nm, preferably between 10 and 300 nm, wherein said electrochemically active material contains at least one compound of the transition metal or transition metals present in the electron collector, characterised by the fact that the electrode is a textile formed by metallic wires or fibres. The invention also relates to a half-accumulator and an accumulator containing such a textile electrode.

L'invention concerne une électrode comprenant (a) un collecteur d'électrons contenant un ou plusieurs métaux de transition des groupes 4 à 12 de la Classification Périodique des Elements, et (b) une matière électrochimiquement active, présente à la surface du collecteur d'électrons sous forme d'une couche de conversion nanostructurée contenant des nanoparticules ou des agglomérats desdites nanoparticules, les nanoparticules ayant un diamètre moyen compris entre 1 et 1000 nm, de préférence entre 10 à 300 nm, ladite matière électrochimiquement active contenant au moins un composé du métal de transition ou des métaux de transition présent(s) dans le collecteur d'électrons, caractérisée par le fait que l'électrode est un textile formé de fils ou de fibres métalliques. L'invention concerne également un demi-accumulateur et un accumulateur contenant une telle électrode textile.
