Title (EN) POWER STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE D’ÉNERGIE
(JA) 蓄電装置
Abstract:
(EN) Provided is a power storage device comprising: a battery stack in which a plurality of secondary batteries and a plurality of spacers are alternately arranged; a pair of end plates disposed on both sides in the first direction of the battery stack; and a compression spring serving as a pressurizing means for pressurizing the battery stack. Each of the secondary batteries includes an electrode body and an outer case. The outer case has a projection that swells towards the inside so as to press the electrode body in the first direction and deforms with expansion of the electrode body.
(FR) L'invention concerne un dispositif de stockage d'énergie comprenant : un empilement de batteries dans lequel une pluralité de batteries secondaires et une pluralité d'entretoises sont agencées en alternance; une paire de plaques d'extrémité disposées des deux côtés dans la première direction de l'empilement de batteries; et un ressort de compression servant de moyen de pressurisation pour mettre sous pression l'empilement de batteries. Chacune des batteries secondaires comprend un corps d'électrode et un boîtier externe. Le boîtier externe a une saillie qui gonfle vers l'intérieur de façon à presser le corps d'électrode dans la première direction et à se déforme avec l'expansion du corps d'électrode.
(JA) 蓄電装置は、二次電池及びスペーサを交互にそれぞれ複数配列してなる電池積層体と、電池積層体の第1方向の両側に設けられた一対のエンドプレートと、電池積層体を加圧する加圧手段である圧縮バネとを備える。二次電池のそれぞれは、電極体と、外装体とを備え、外装体は、内側に膨出して電極体を第1方向に押圧すると共に電極体の膨張に伴って変形する凸部を有する。
