Abstract

La présente invention concerne une cellule secondaire à électrolyte non aqueux dans laquelle un groupe électrode (4), sur lequel sont bobinées une plaque électrode positive (1) et une plaque électrode négative (2), obtenues en enduisant un collecteur en utilisant une couche de substance active, un séparateur (3) se trouvant entre lesdites plaques électrodes, est logé dans un boîtier de cellule (7). Parmi la plaque électrode positive et la plaque polaire négative, la plaque polaire qui est de la polarité opposée à celle du boîtier de cellule comporte, à la circonférence la plus extérieure du groupe électrode, une première partie exposée de collecteur (21) dans laquelle un collecteur d'au moins un bobinage est exposé, et une seconde partie exposée de collecteur (22) formée dans une partie séparée de la première partie exposée de collecteur. Une première languette de collecteur (11) est disposée dans la première partie exposée de collecteur, et une seconde languette de collecteur (12) est prévue sur la seconde partie exposée de collecteur. Les première et seconde languettes de collecteur sont connectées à l'extérieur du groupe électrode.
