Title (EN) SECONDARY BATTERY AND PRODUCTION METHOD THEREFOR
(FR) BATTERIE SECONDAIRE, ET PROCÉDÉ DE PRODUCTION ASSOCIÉ
(JA) 二次電池とその製造方法
Abstract:
(EN) A secondary battery having: a power generation element (4) having positive electrodes (1) and negative electrodes (2) laminated therein, via separators (3); and an outer case (5) housing the power generation element (4) and an electrolyte (6), and having the outer circumference thereof sealed. The electrolyte (6) has a static viscosity at 25°C of 4-30 cP. The positive electrodes (1) and negative electrodes (2) include collectors (1a, 2a) and active substances (1b, 2b) coated on one or both surfaces of the collectors (1a, 2a). Both the active substance (1b) for the positive electrodes (1) and the active substance (2b) for negative electrodes (2) have an overall porosity of at least 30% but less than 50%.
(FR) Batterie secondaire, comprenant : un élément de génération de puissance (4), comportant des électrodes positives (1) et des électrodes négatives (2) stratifiées à l'intérieur, via des séparateurs (3) ; et un boîtier extérieur (5), logeant l'élément de génération de puissance (4) et un électrolyte (6), et dont la circonférence externe est scellée. L'électrolyte (6) a une viscosité statique à 25 °C comprise entre 4 et 30 cP. Les électrodes positives (1) et les électrodes négatives (2) comprennent des collecteurs (1a, 2a) et des substances actives (1b, 2b) déposées sur l'une ou sur les deux surfaces des collecteurs (1a, 2a). La substance active (1b) pour les électrodes positives (1) et la substance active (2b) pour les électrodes négatives (2) ont toutes les deux une porosité globale d'au moins 30 %, mais inférieure à 50 %.
(JA)  二次電池が、正極1と負極2がセパレータ3を介して積層されている発電要素4と、発電要素4と電解液6とを収容し外周部が封止されている外装体5とを有する。電解液6は、25℃における静粘度が4cP以上かつ30cP以下である。正極1と負極2は、集電体1a,2aと、集電体1a,2aの両面または片面に塗布された活物質1b,2bとを含む。正極1の活物質1bと負極2の活物質2bはそれぞれ、全体にわたって30%以上かつ50%未満の空孔率を有している。
