Title (EN) CYLINDRICAL BATTERY
(FR) BATTERIE CYLINDRIQUE
(JA) 円筒形電池
Abstract:
(EN) This cylindrical battery is provided with: an electrode group obtained by rolling up a positive electrode, a negative electrode, and a first separator interposed therebetween, which all have a belt-like shape; an electrolyte; a bottomed cylindrical battery case; and an opening sealing plate. The negative electrode is provided with a negative electrode collector and negative electrode active material layers formed on both surfaces of the negative electrode collector. The negative electrode has a thin part provided at an area within a length L3 from the outer end of the negative electrode; a tapered part adjacent to the thin part; and a body part other than these parts. The thickness of the negative electrode active material layer on the outer peripheral side of the tapered part is gradually reduced from the body part side toward the thin part side. The electrode group is formed such that the outer end of the positive electrode overlaps the tapered part via the first separator, and further includes a second separator interposed between the tapered part and the outer end of the positive electrode.
(FR) Cette batterie cylindrique est pourvue : d'un groupe d'électrodes obtenu par enroulement d'une électrode positive, d'une électrode négative, et d'un premier séparateur intercalé entre celles-ci, qui présentent tous une forme de ceinture ; d'un électrolyte ; d'un boîtier de batterie cylindrique à fond ; et d'une plaque d'étanchéité d'ouverture. L'électrode négative comporte un collecteur d'électrode négative et des couches de matière active d'électrode négative formées sur les deux surfaces du collecteur d'électrode négative. L'électrode négative présente une partie mince au niveau d'une zone à l'intérieur d'une longueur L3 à partir de l'extrémité extérieure de l'électrode négative ; une partie conique adjacente à la partie mince ; et une partie de corps autre que ces parties. L'épaisseur de la couche de matière active d'électrode négative sur le côté périphérique extérieur de la partie conique est progressivement réduite du côté partie de corps au côté partie mince. Le groupe d'électrodes est formé de telle sorte que l'extrémité extérieure de l'électrode positive recouvre la partie conique via le premier séparateur, et comprend en outre un second séparateur intercalé entre la partie conique et l'extrémité extérieure de l'électrode positive.
(JA) 円筒形電池は、いずれも帯状の正極、負極、およびこれらの間に介在する第1セパレータが巻回された電極群と、電解質と、有底円筒形の電池ケースと、封口板と、を備える。負極は、負極集電体と、負極集電体の両方の表面に形成された負極活物質層とを備え、負極の外端から長さL3の領域に設けられた薄肉部と、薄肉部に隣接するテーパ部と、それ以外の本体部とを備える。テーパ部の外周側の負極活物質層の厚みは、本体部側から薄肉部側に向かって傾斜的に小さくなっている。電極群は、正極の外端が、第1セパレータを介してテーパ部と重なるように配されており、かつ正極の外端とテーパ部との間に配された第2セパレータをさらに含む。
