Title (EN) LITHIUM ION SECONDARY BATTERY AND METHOD FOR MANUFACTURING SAME
(FR) BATTERIE RECHARGEABLE LITHIUM-ION ET SON PROCÉDÉ DE FABRICATION
(JA) リチウムイオン二次電池及びその製造方法
Abstract: front page image
(EN) Disclosed is a method for manufacturing a lithium ion secondary battery, which has positive electrodes and negative electrodes, each of said positive electrodes and each of said negative electrodes being disposed with a separator therebetween, and which is housed, with an electrolytic solution, in an outer case configured from a flexible film. In the method, the quantity of dissolved nitrogen in the electrolytic solution when filling the outer case with the electrolytic solution is equal to or less than 100μg/ml.
(FR) L'invention concerne un procédé de fabrication d'une batterie rechargeable lithium-ion, qui comporte des électrodes positives et des électrodes négatives, chacune desdites électrodes positives et chacune desdites électrodes négatives étant disposées avec un séparateur entre elles, et qui est logée, avec une solution électrolytique, dans un boîtier externe configuré à partir d'un film souple. Dans le procédé, la quantité d'azote dissous dans la solution électrolytique lors du remplissage du boîtier extérieur avec la solution électrolytique est égale ou inférieure à 100 μg/ml.
(JA)  正極および負極がセパレータを介して配置され、電解液とともに、可撓性フィルムからなる外装ケースに収容されたリチウムイオン二次電池の製造方法において、前記電解液を前記外装ケース内に注液する際の電解液中の溶存窒素の量を100μg/ml以下とする製造方法。
