Title
(EN) METHOD FOR MANUFACTURING OF SLURRY FOR PRODUCTION OF BATTERY FILM
(FR) PROCÉDÉ POUR LA FABRICATION DE SUSPENSION POUR LA PRODUCTION DE FILM DE BATTERIE
Abstract
(EN) The present invention deals with a process for description of a slurry for coating of electrodes for use in lithium ion batteries, where the process as a minimum comprises the steps of a) mix (1) active materials (A) with a binder (B) into a binder solution, and b) add (1) an organic carbonate (C) to a binder solution so that a slurry is generated and the invention is comprising a method for generation of electrodes for a lithium battery cell, where the procedure as a minimum comprises the steps of a) mix (1) active materials (A) with a binder (B) with a binder solution b) add (1) an organic carbonate (C) into a binder solution so that a slurry is generated, c) coat (2) an electrode material (D) with the slurry, d) evaporate/ dry (3) the coating of the electrode material meaning that the organic carbonate (C) is steamed/ dried, and e) surface finishing (5,6,7) the slurry so that the electrode is prepared for use in a lithium ion battery cell. Finally the invention states a procedure for manufacturing of a lithium battery cell.
(FR) La présente invention concerne un procédé pour la fabrication d'une suspension pour le revêtement d'électrodes destinées à être utilisées dans des batteries au lithium-ion, le procédé comprenant au moins les étapes suivantes: a) le mélange (1) de matériaux actifs (A) avec un liant (B) en une solution de liant, et b) l'ajout (1) d'un carbonate organique (C) à une solution de liant afin de générer une suspension. L'invention concerne également un procédé pour la génération d'électrodes pour une cellule de batterie au lithium, ledit procédé comprenant au moins les étapes suivantes: a) le mélange (1) de matériaux actifs (A) avec un liant (B) avec une solution de liant, et b) l'ajout (1) d'un carbonate organique (C) à une solution de liant afin de générer une suspension, c) le revêtement (2) d'un matériau d'électrode (D) avec la suspension, d) l'évaporation/le séchage (3) du revêtement du matériau d'électrode, c'est-à-dire, la vaporisation/le séchage du carbonate organique, et e) la finition de surface (5, 6, 7) de la suspension de sorte que l'électrode soit prête à être utilisée dans une cellule de batterie au lithium-ion. L'invention concerne enfin un procédé pour la fabrication d'une cellule de batterie au lithium-ion.
