Title
(EN) INTERMITTENTLY COATED DRY ELECTRODE FOR ENERGY STORAGE DEVICE AND METHOD OF MANUFACTURING THE SAME
(FR) ÉLECTRODE SÈCHE À REVÊTEMENT INTERMITTENT POUR DISPOSITIF DE STOCKAGE D'ÉNERGIE ET SON PROCÉDÉ DE FABRICATION
Abstract
(EN)
Methods for manufacturing intermittently coated dry electrodes for energy storage devices and energy storage devices including the intermittently coated dry electrodes are disclosed. In one embodiment, the method includes providing a metal layer and providing an electrochemically active free-standing film formed of a dry active material. The method also includes combining the electrochemically active free-standing film and the metal layer to form a combined layer. The method further includes removing a portion of the electrochemically active free-standing film from the combined layer so that the electrochemically active free-standing film is intermittently formed on the metal layer in a longitudinal direction of the metal layer.

L'invention concerne des procédés de fabrication d'électrodes sèches à revêtement intermittent pour des dispositifs de stockage d'énergie et des dispositifs de stockage d'énergie comprenant les électrodes sèches à revêtement intermittent. Selon un mode de réalisation, le procédé comprend la fourniture d'une couche métallique et la fourniture d'un film autonome électrochimiquement actif constitué d'un matériau actif sec. Le procédé comprend également la combinaison du film autonome électrochimiquement actif et de la couche métallique pour former une couche combinée. Le procédé comprend en outre l'élimination d'une partie du film autonome électrochimiquement actif à partir de la couche combinée de telle sorte que le film autonome électrochimiquement actif est formé par intermittence sur la couche métallique dans une direction longitudinale de la couche métallique.
