Title
(EN) METHOD FOR PRODUCING LITHIUM ION SECONDARY BATTERY
(FR) DISPOSITIF DE PRODUCTION D'UNE BATTERIE SECONDAIRE AU LITHIUM-ION
(JA) リチウムイオン二次電池の製造方法
Abstract
(EN)
[Problem] To provide a method for producing a secondary battery which has a high capacity and in which the degradation thereof due to charging and discharging at a high potential is inhibited. [Solution] A method for producing a lithium ion secondary battery in which positive electrodes 150, heat-resistant-insulating-layer-provided separators 17 having a heat-resistant insulating layer comprising oxide particles on one surface of a porous resin base body, and negative electrodes 130 are stacked together, and the heat-resistant-insulating-layer-provided separators 17 are impregnated with a non-aqueous electrolyte, the method being characterized by having a drying step for drying, before the stacking, the heat-resistant-insulating-layer-provided separators so that the water content of the heat-resistant-insulating-layer-provided separators 17 remains within a predetermined range.

Le problème à résoudre dans le cadre de la présente invention est de fournir un procédé de production d'une batterie secondaire qui présente une capacité élevée et dont la dégradation due à la charge et à la décharge à un potentiel élevé est empêchée. La solution selon l'invention concerne un procédé de production d'une batterie secondaire au lithium-ion dans laquelle des électrodes positives (150), des séparateurs dotés d'une couche isolante résistant à la chaleur (17) ayant une couche isolante résistant à la chaleur comprenant des particules d'oxyde sur une surface d'un corps de base en résine poreuse, et des électrodes négatives (130) sont empilés ensemble et les séparateurs dotés d'une couche isolante résistant à la chaleur (17) sont imprégnés d'un électrolyte non aqueux. Le procédé est caractérisé en ce qu'il comporte une étape de séchage afin de sécher, avant l'empilement, les séparateurs dotés d'une couche isolante résistant à la chaleur de sorte que la teneur en eau des séparateurs dotés d'une couche isolante résistant à la chaleur (17) reste au sein d'une plage prédéfinie.
