要約
(EN)
Provided is a laminated secondary battery characterized in that anodes (5) and cathodes (4), in which anode collecting tabs (57) and cathode collecting tabs (47) are formed on an anode collector (51) made of a metal foil and a cathode collector (41) made of a metal foil integrally therewith, are laminated through separators (6), in that the separators (6) are also arranged at positions (8) where the anode collecting tabs and the cathode collecting tabs face each other, and in that an anode lead (17) connected with the anode collecting tabs and a cathode lead (15) connected with the cathode collecting tabs are extracted from the common end face of the laminate of the anodes (5) and the cathodes (4) to the outside of an armoring member (3).
(FR)
L'invention concerne un accumulateur stratifié caractérisé en ce que les anodes (5) et les cathodes (4), dans lesquelles les languettes collectrices d'anode (57) et les languettes collectrices de cathode (47) sont formées sur un collecteur d'anode (51) constitué d'une feuille de métal et un collecteur de cathode (41) constitué d'une feuille de métal intégrés, sont stratifiées à travers des séparateurs (6), en ce que les séparateurs (6)sont aussi disposés en des positions (8) où les languettes collectrices d'anode et les languettes collectrices de cathode se font face, et en ce qu'un conducteur d'anode (17) connecté aux languettes collectrices d'anode et un conducteur de cathode (15) connecté aux languettes collectrices de cathode sont extraits de la face d'extrémité commune du stratifié des anodes (5) et des cathodes (4) à l'extérieur d'un élément de blindage (3).
(JA)
 金属箔製の正極集電体51と金属箔製の負極集電体41上に、正極集電タブ57、負極集電タブ47を一体に形成した正極5と負極4をセパレータ6を介して積層し、セパレータ6は、正極集電タブと負極集電タブの対向部分8にも配置されており、前記正極集電タブに接続された正極リード17と、前記負極集電タブに接続された負極リード15は、正極5、負極4の積層体の同一端面から外装材3の外部へ取り出されていることを特徴とする積層型二次電池。
