Abstract
(EN)
This method for producing a laminate-type secondary battery comprises a step in which heat bars 51 are brought into contact with the part of a laminate casing 40, which houses an electrode body 5, where casing materials 41 of the laminate casing are oppositely disposed, and as a result thereof, the oppositely disposed casing materials 41 are welded together. The heat bars contact contact-regions CT1 positioned on the inside of a peripheral edge ce of the laminate casing.
(FR)
Ce procédé de fabrication d'une batterie rechargeable de type stratifié comprend une étape au cours de laquelle des barres thermiques 51 sont mises en contact avec la partie d'un boîtier stratifié 40, qui loge un corps d'électrode 5, les matériaux de boîtier 41 du boîtier stratifié étant disposés de façon opposée, et en conséquence, les matériaux de boîtier 41 disposés de façon opposée étant soudés ensemble. Les barres thermiques entrent en contact avec des régions de contact CT1 positionnées sur l'intérieur d'un bord périphérique ce du boîtier stratifié.
(JA)
ラミネート型二次電池の製造方法は、電極体5を収容するラミネート外装体40の外装材41が対向して配置されている部分にヒートバー51を接触させて対向して配置された外装材41を溶着する工程を含む。ヒートバーは、ラミネート外装体の周縁部ceの内側に位置する接触領域CT1に接触する。
