Title (EN) SECONDARY CELL AND CELL PACK
(FR) CELLULE SECONDAIRE ET BLOC DE CELLULES
(JA) 二次電池及び電池パック
Abstract:
(EN) A cell pack that is one example of an embodiment of the present invention is provided with a plurality of secondary cells, and a plurality of spacers interposed between the secondary cells. Each secondary cell is provided with: a laminate-type electrode body in which a plurality of positive electrodes and a plurality of negative electrodes are laminated in alternating fashion in a first direction with separators interposed therebetween; and an outer packaging body including side wall sections that deform according to expansion of the electrode body. Projecting parts projecting toward the inner side of the side wall sections are formed in the side wall sections. The electrode bodies are contained within the outer packaging body in a state pressed in the first direction and held by the projecting parts.
(FR) Un bloc de cellules qui est un exemple d'un mode de réalisation de la présente invention comporte une pluralité de cellules secondaires, et une pluralité d’espaceurs interposés entre les cellules secondaires. Chaque cellule secondaire comprend : un corps d'électrode de type stratifié dans lequel une pluralité d'électrodes positives et une pluralité d'électrodes négatives sont stratifiées de manière alternée dans une première direction avec des séparateurs interposés entre celles-ci; et un corps d'emballage externe comprenant des sections de paroi latérale qui se déforment en fonction de l'expansion du corps d'électrode. Des parties saillantes faisant saillie vers le côté interne des sections de paroi latérale sont formées dans les sections de paroi latérale. Les corps d'électrode sont contenus à l'intérieur du corps d'emballage externe dans un état comprimé dans la première direction et maintenus par les parties saillantes.
(JA) 実施形態の一例である電池パックは、複数の二次電池と、各二次電池の間に介在する複数のスペーサとを備える。二次電池は、複数の正極と複数の負極がセパレータを介して第1方向に交互に積層された積層型の電極体と、電極体の膨張に伴って変形する側壁部を含む外装体とを備える。側壁部には、側壁部の内側に膨出した凸部が形成されている。電極体は、凸部によって第1方向に押圧され、保持された状態で外装体内に収容される。
