Abstract:
(EN) The present invention provides a secondary cell capable of suppressing the adverse effects caused by the folded portion of a zigzag shaped separator. A secondary cell (1) comprises a plurality of flat-shaped positive electrodes (100), a plurality of flat-shaped negative electrodes (200), and a strip-shaped separator (300) provided between the positive electrodes (100) and negative electrodes (200). The positive electrodes (100) and the negative electrodes (200) are alternately laminated with the separator (300) interposed therebetween. The separator (300) is formed into a zigzag shape to interpose the separator between the positive electrodes (100) and the negative electrodes (200). The folded portion of the zigzag separator (300) is provided so that the folded portion is at least a predetermined length away from the end of the negative electrode (200).
(FR) La présente invention concerne un accumulateur capable de supprimer les effets indésirables provoqués par la partie repliée d'un séparateur en forme de zigzag. Un accumulateur (1) comprend une pluralité d'électrodes positives en forme plate (100), une pluralité d'électrodes négatives en forme plate (200), et un séparateur en forme de bande (300) disposé entre les électrodes positives (100) et les électrodes négatives (200). Les électrodes positives (100) et les électrodes négatives (200) sont stratifiées en alternance avec le séparateur (300) interposé entre elles. Le séparateur (300) est formé en une forme en zigzag pour interposer le séparateur entre les électrodes positives (100) et les électrodes négatives (200). La partie repliée du séparateur en zigzag (300) est disposée de telle sorte que la partie repliée est d'au moins une longueur prédéterminée à l'opposé de l'extrémité de l'électrode négative (200).
(JA) つづら折りされたセパレータの折り目部分に起因する悪影響の発生を抑制することができる二次電池を提供する。二次電池(1)は、複数の扁平形状の正極(100)と、複数の扁平形状の負極(200)と、正極(100)と負極(200)との間に設けられた帯状のセパレータ(300)とを有する。正極(100)及び負極(200)は、セパレータ(300)を間に介在させた状態で交互に積層されている。セパレータ(300)は、正極(100)と負極(200)との間に介在するようにつづら折りにされている。セパレータ(300)のつづら折りの折り目部分は、折り目部分から負極(200)の端部までが少なくとも予め定められた長さだけ離れるように、設けられている。
