Abstract:
(EN) A cell is provided with: an electrode group having a first electrode, a second electrode, and a separator interposed between the first electrode and the second electrode; an electrolyte; a container for accommodating the electrode group and the electrolyte; a sealing member for sealing an opening of the container; and a first lead for electrically connecting the first electrode and the sealing member to each other. The first lead has a region welded to the sealing member. The welded region has at least one raised part oriented along the long direction of the first lead. The cross-section at the boundary between the welded region and the non-welded region on the first electrode side has a convex shape corresponding to the raised part.
(FR) L'invention porte sur une pile qui comprend : un groupe d'électrodes comportant une première électrode, une seconde électrode et un séparateur intercalé entre la première électrode et la seconde électrode ; un électrolyte ; un contenant pour loger le groupe d'électrodes et l'électrolyte ; un élément d'étanchéité pour fermer hermétiquement une ouverture du contenant ; et un premier conducteur pour connecter électriquement la première électrode et l'élément d'étanchéité l'un à l'autre. Le premier conducteur comporte une zone soudée à l'élément d'étanchéité. La zone soudée comporte au moins une partie surélevée orientée selon la direction longitudinale du premier conducteur. La section transversale au niveau de la limite entre la zone soudée et la zone non soudée du côté de la première électrode présente une forme convexe correspondant à la partie surélevée.
(JA) 電池は、第1電極と、第2電極と、第1電極と第2電極との間に介在するセパレータと、を有する電極群と、電解質と、電極群と電解質とを収容する容器と、容器の開口を塞ぐ封口部材と、第1電極と封口部材とを電気的に接続する第1リードと、を具備する。第1リードが、封口部材との溶着領域を有し、溶着領域は、第1リードの長手方向に沿った少なくとも1つの隆起部を有し、溶着領域と第1電極側の溶着されていない領域との境界における断面が、隆起部に対応する凸形状を有する。
