Abstract:
(EN) The present invention relates to a secondary battery comprising: a plurality of basic unit bodies having first electrodes and second electrodes laminated alternatively with separating membranes interposed therebetween; and an electrode assembly having separating films provided to surround the plurality of basic unit bodies such that the same are laminated repeatedly. The electrode assembly comprises protective unit bodies laminated on the outermost separating film, which is positioned on the uppermost end or the lowermost end among the separating films, respectively. The protective unit bodies are structured such that a second protective electrode, a separating membrane, and a first protective electrode are successively laminated on the outermost separating film positioned on the uppermost end or the lowermost end of the electrode assembly. The second protective electrode has a section coating structure so as to comprise a second collector and a second electrode active material portion having a second electrode active material with which the inner surface of the second collector is coated. The inner surface may be a surface that faces the center of the electrode assembly.
(FR) La présente invention concerne une batterie rechargeable comprenant : une pluralité de corps unitaires de base ayant des premières électrodes et des secondes électrodes stratifiées en alternance avec des membranes de séparation interposées entre celles-ci ; et un ensemble électrode ayant des films de séparation disposés de façon à entourer la pluralité de corps unitaires de base de telle sorte que ceux-ci sont stratifiés de manière répétée. L'ensemble électrode comprend des corps unitaires de protection stratifiés sur le film de séparation le plus à l'extérieur, qui est positionné sur l'extrémité supérieure ou l'extrémité inférieure parmi les films de séparation, respectivement. Les corps unitaires de protection sont structurés de telle sorte qu'une seconde électrode de protection, une membrane de séparation et une première électrode de protection sont successivement stratifiées sur le film de séparation le plus à l'extérieur positionné sur l'extrémité supérieure ou l'extrémité inférieure de l'ensemble électrode. La seconde électrode de protection a une structure de revêtement de section de façon à comprendre un second collecteur et une seconde partie de matériau actif d'électrode ayant un second matériau actif d'électrode avec lequel est revêtue la surface interne du second collecteur. La surface interne peut être une surface qui fait face au centre de l'ensemble électrode.
