Abstract
(EN) Provided are an assembled battery and a battery pack that are easy to design and assemble and that make it possible to suppress destruction of a battery case and any decrease in performance of a battery due to deformation of a battery cell while suppressing transmission of heat between battery cells when there is an abnormality. Each battery cell (2) has an electrode surface (2a) that has an electrode (3), and an outer peripheral surface (2b) that is a surface orthogonal to the electrode surface (2a). The battery cells (2) are connected in series or in parallel with the electrode (3) and a connector, etc. (not shown), interposed therebetween. The outer peripheral surfaces of the battery cells (2) are covered by a flameproof material (4), and the outer peripheral surface of the flameproof material (4) is furthermore covered by an elastic member (5), whereby an assembled battery (6) is configured. The elastic member (5) is a cylindrical body of which both ends are open, and the elastic member (5) covers the outer peripheral surfaces of the battery cells (2) and the flameproof material (4) in the circumferential direction.
(FR) L'invention concerne une batterie assemblée et une batterie qui sont faciles à concevoir et à assembler et qui permettent de supprimer la destruction d'un boîtier de batterie et toute diminution de performance d'une batterie due à la déformation d'une cellule de batterie tout en supprimant la transmission de chaleur entre des cellules de batterie lorsqu'il y a une anomalie. Chaque cellule de batterie (2) a une surface d'électrode (2a) qui a une électrode (3), et une surface périphérique externe (2b) qui est une surface orthogonale à la surface d'électrode (2a). Les cellules de batterie (2) sont connectées en série ou en parallèle à l'électrode (3) et un connecteur, etc. (non représenté), interposé entre elles. Les surfaces périphériques externes des cellules de batterie (2) sont recouvertes d'un matériau ignifuge (4), et la surface périphérique externe du matériau ignifuge (4) est en outre recouverte par un élément élastique (5), moyennant quoi une batterie assemblée (6) est configurée. L'élément élastique (5) est un corps cylindrique dont les deux extrémités sont ouvertes, et l'élément élastique (5) recouvre les surfaces périphériques externes des cellules de batterie (2) et le matériau ignifuge (4) dans la direction circonférentielle.
(JA) 異常時における各電池セル間の熱の伝播を抑制しつつ、電池セルの変形による電池ケースの破壊及び電池の性能の低下を抑制することができ、設計及び組立が容易である組電池及び電池パックを提供する。各電池セル(2)は、電極(3)を有する電極面(2a)と、電極面(2a)に直交する面である外周面(2b)とを有し、各電池セル(2)は、電極(3)及び不図示のコネクタ等を介して直列又は並列に接続されている。電池セル(2)の外周面は防炎材(4)により被覆され、さらに防炎材(4)の外周面は弾性部材(5)により被覆されており、これにより、組電池(6)が構成される。弾性部材(5)は両端部が開口した筒状体であり、電池セル(2)及び防炎材(4)の外周面を周方向に被覆している。
