Title (EN) METHOD FOR MANUFACTURING A LITHIUM-ION BATTERY
(FR) PROCEDE DE FABRICATION D'UN ACCUMULATEUR DU TYPE LITHIUM-ION
Abstract:
(EN) The invention relates to a method for producing a lithium-ion battery comprising a positive electrode and a negative electrode arranged on either side of an electrolyte, the positive electrode comprising, as an active material, a lithium-based material, the method comprising the following steps: a) a step of depositing a film containing a lithium salt on the surface of the positive electrode before it is placed in the battery; b) a step of assembling the positive electrode, the negative electrode and the electrolyte; and c) a step of forming a passivation layer on the surface of the negative electrode with the lithium ions resulting from the decomposition of the lithium salt contained in the film by applying a first charge to the aforementioned assembly.
(FR) L'invention a trait à un procédé de préparation d'un accumulateur lithium-ion comprenant une électrode positive et une électrode négative disposées de part et d'autre d'un électrolyte, ladite électrode positive comprenant, comme matériau actif, un matériau à base de lithium, ledit procédé comprenant les étapes suivantes: a) une étape de dépôt à la surface de l'électrode positive, avant placement dans l'accumulateur, d'un film contenant un sel de lithium; b) une étape d'assemblage de l'électrode positive, de l'électrode négative et de l'électrolyte; et c) une étape de formation d'une couche de passivation à la surface de l'électrode négative avec les ions lithium issus de la décomposition du sel de lithium contenu dans le film par application d'une première charge à l'assemblage susmentionné.
