Title
(EN) LAMINATED BATTERY AND MANUFACTURING METHOD THEREFOR
(FR) BATTERIE STRATIFIÉE, ET PROCÉDÉ DE FABRICATION DE CELLE-CI
(JA) ラミネート電池及びその製造方法
Abstract
(EN) A laminated battery (10) is provided with an electricity-producing element and an outer case (11). The electricity-producing element contains a positive electrode, a negative electrode, and an electrolyte. The outer case (11) comprises two sheets of laminating film (20, 30) and includes the following: a containing section (12) that contains the electricity-producing element; and a sealing section (13) that is formed around the edge of the containing section (12) by bonding the sheets of laminating film to each other. Corners (17) are formed along the boundary between the containing section (12) and the sealing section (13), and an adhesive resin layer (M) in the sealing section (13) is thicker in corner regions (18) near the aforementioned corners than in other regions.
(FR) La batterie stratifiée (10) de l'invention est équipée : d'un élément générateur d'électricité contenant une électrode négative, une électrode positive et un électrolyte; et d'un corps d'enveloppe (11) qui est configuré par deux films de stratification (20, 30), et qui contient une partie admission (12) pour l'élément générateur d'électricité, et une partie scellement (13) liant les deux films entre eux, et formée sur le bord périphérique de la partie admission (12). Une partie angle (17) est formée au niveau d'une interface entre la partie admission (12) et la partie scellement (13). La partie scellement (13) présente une couche de résine d'adhésion (M) dont l'épaisseur dans une région angle (18) proche de l'angle, est supérieure à son épaisseur dans les autres régions.
(JA)  ラミネート電池10は、正極、負極、及び電解質を含む発電要素と、2枚のラミネートフィルム20,30から構成された外装体11であって、発電要素の収容部12、及び当該各フィルム同士を接合して収容部12の周縁に形成された封止部13を含む外装体11とを備える。そして、収容部12と封止部13との境界に角部17が形成され、封止部13は、当該角に近接した角領域18における接着樹脂層Mの厚みが、他の領域における接着樹脂層Mの厚みよりも大きい。
