Title (EN) METHODS OF PREPARING ELECTROCHEMICAL CELLS
(FR) PROCEDES DE PREPARATION DE CELLULES ELECTROCHIMIQUES
Abstract:
(EN) Methods of preparing a cathode/separator assembly for use in electrochemical cells in which a protective coating layer, such as a single ion conducting layer, is coated on a temporary carrier substrate, a microporous separator layer is then coated on the protective coating layer, and a cathode active layer is then coated on the separator layer, prior to removing the temporary carrier substrate from the protective coating layer. Additional layers, including an edge insulating layer, a cathode current collector layer, an electrode insulating layer, an anode current collector layer, an anode layer such as a lithium metal layer, and an anode protective layer, such as a single ion conducting layer, may be applied subsequent to the coating step of the microporous separator layer. Also, methods of preparing electrochemical cells utilizing cathode/separator assemblies prepared by such methods, and cathode/separator assemblies and electrochemical cells prepared by such methods.
(FR) L'invention concerne des procédés de préparation d'un ensemble cathode/séparateur s'utilisant dans des cellules électrochimiques, selon lesquels une couche de revêtement protectrice, telle qu'une couche conductrice à ion unique, revêtant un substrat support temporaire est elle-même revêtue d'une couche de séparation microporeuse, une couche cathodique étant déposée sur la couche de séparation avant l'élimination du substrat temporaire depuis la couche de revêtement protectrice. On peut appliquer des couches supplémentaires, telles qu'une couche d'isolation des bords, une couche collecteur cathodique de courant, une couche d'isolation d'électrode, une couche collecteur anodique de courant, une couche anodique telle qu'une couche métallique en lithium, et une couche de protection anodique, telle qu'une couche conductrice à ion unique, à la suite de l'étape de revêtement de la couche de séparation microporeuse. L'invention concerne également des procédés de fabrication de cellules électrochimiques utilisant les ensembles cathode/séparateur obtenus selon lesdits procédés, ainsi que des ensembles cathode/séparateur et des cellules électrochimiques obtenus par ces procédés.
