Title (EN) ELECTRODE ASSEMBLY AND MANUFACTURING METHOD FOR POWER STORAGE DEVICE
(FR) ENSEMBLE D’ÉLECTRODE, ET PROCÉDÉ DE FABRICATION DE DISPOSITIF DE STOCKAGE
(JA) 電極組立体及び蓄電装置の製造方法
Abstract:
(EN) This electrode assembly which includes an electrode having a tab, is provided with: a current collector; and a tab laminate which includes laminated tabs. The tab laminate is disposed on the current collector in the lamination direction of the tab laminate. The tab laminate includes a welded portion which is positioned on the inner side with respect to a first end surface, of the tab laminate, extending in the lamination direction of the tab laminate. In a plane orthogonal to the lamination direction of the tab laminate, the welded portion has a cross sectional area which monotonically increases, over the thickness of the tab laminate, toward the current collector. In a cross section, of the tab laminate, that includes the lamination direction of the tab laminate and is orthogonal to the first end surface of the tab laminate, the outer surface of the welded portion is inclined with respect to the lamination direction of the tab laminate such that the outer surface extends outwardly in approaching the current collector.
(FR) Selon l’invention, un ensemble d’électrode équipé d’une électrode contenant une languette, est équipé : d’un collecteur, et d’un stratifié de languettes possédant des languettes stratifiées. Le stratifié de languettes est disposé sur le collecteur dans la direction de stratification du stratifié de languettes. Le stratifié de languettes possède une partie soudage qui est positionnée côté interne à partir d’une première face extrémité du stratifié de languettes se prolongeant suivant la direction de stratification du stratifié de languettes. La surface transversale de la partie soudage dans un plan perpendiculaire à la direction de stratification du stratifié de languettes, augmente de manière monotone en s’approchant du collecteur, dans l’épaisseur du stratifié de languettes. Une face externe de la partie soudage est inclinée dans la direction de stratification du stratifié de languettes de manière à s’orienter vers un côté externe en s’approchant du collecteur, dans un plan transversal du stratifié de languettes incluant la direction de stratification du stratifié de languettes et perpendiculaire à la première face extrémité du stratifié de languettes.
(JA) タブを含む電極を備える電極組立体は、集電体と、積層されたタブを有するタブ積層体と、を備える。タブ積層体が、タブ積層体の積層方向において集電体上に配置される。タブ積層体が、タブ積層体の積層方向に沿って延在するタブ積層体の第1の端面から内側に位置する溶接部を有する。タブ積層体の積層方向に直交する平面における溶接部の断面積が、タブ積層体の厚みにわたって、集電体に近づくに連れて単調増加している。タブ積層体の積層方向を含みタブ積層体の第1の端面に直交するタブ積層体の断面において、溶接部の外面が、集電体に近づくに連れて外側に向かうようにタブ積層体の積層方向に対して傾斜している。
