Title
(EN) METHODS TO FABRICATE VARIATIONS IN POROSITY OF LITHIUM ION BATTERY ELECTRODE FILMS
(FR) PROCÉDÉS POUR FABRIQUER DES VARIATIONS DE POROSITÉ DE FILMS D'ÉLECTRODES DE BATTERIES LITHIUM-IONS
Abstract
(EN)
A method and apparatus for forming lithium-ion batteries and battery cell components, and more specifically, to a system and method for fabricating such batteries and battery cell components using deposition processes that form three-dimensional porous structures are provided. One method comprises texturing a conductive substrate by calendering the conductive substrate between opposing wire mesh structures, forming a first layer of cathodically active material having a first porosity on the surface of the textured conductive substrate, and forming a second layer of cathodically active material having a second porosity on the first layer, wherein the second porosity is greater than the first porosity.
(FR)
L'invention porte sur un procédé et sur un appareil pour former des batteries lithium-ions et des composants d'éléments de batterie, et, plus spécifiquement, sur un système et sur un procédé pour fabriquer de telles batteries et de tels composants d'éléments de batterie à l'aide de processus de dépôt qui forment des structures poreuses en trois dimensions. Un procédé comprend le texturage d'un substrat conducteur par calandrage du substrat conducteur entre des structures de treillis de fils opposées, la formation d'une première couche de matériau actif de façon cathodique ayant une première porosité sur la surface du substrat conducteur texturé, et la formation d'une seconde couche de matériau actif de façon cathodique ayant une seconde porosité sur la première couche, la seconde porosité étant supérieure à la première porosité.
