Title (EN) POWER STORAGE APPARATUS AND METHOD FOR MANUFACTURING POWER STORAGE APPARATUS
(FR) APPAREIL DE STOCKAGE D’ÉNERGIE ET PROCÉDÉ DE FABRICATION D’UN APPAREIL DE STOCKAGE D’ÉNERGIE
(JA) 蓄電装置及び蓄電装置の製造方法
Abstract:
(EN) This power storage apparatus is provided with: an electrode assembly that is formed by alternately laminating positive and negative electrodes with a separator therebetween; a case body that houses the electrode assembly; and a lid member that closes the opening of the case body. The bottom side end edge and the lateral end edge of the positive electrode are positioned inward of the bottom side end edge and the lateral end edge of the negative electrode. Rounded corners are formed at the intersections between the inner surfaces of the side walls of the case body and the inner bottom surface of the bottom wall of the case body. A gap is present between the bottom surface of the electrode assembly and the inner bottom surface of the case body, and the size of the gap in the depth direction is larger by 1-1.5 times than the radius of the corners.
(FR) L’appareil de stockage d’énergie selon l’invention comprend : un ensemble d’électrodes qui est formé par empilage en alternance d’électrodes positives et négatives avec un séparateur entre elles ; un boîtier qui loge l’ensemble d’électrodes ; et un élément couvercle qui ferme l’ouverture dans le corps du boîtier. Le bord d’extrémité côté fond et le bord d’extrémité latéral de l’électrode positive sont positionnés vers l’intérieur du bord d’extrémité côté fond et du bord d’extrémité latéral de l’électrode négative. Des coins arrondis sont formés aux intersections entre les surfaces internes des parois latérales du corps du boîtier et la surface de fond interne de la paroi de fond du corps de boîtier. Un espace est présent entre la surface de fond de l’ensemble d’électrodes et la surface de fond interne du corps de boîtier, et la dimension de l’espace dans le sens de la profondeur est plus grande de 1 à 1,5 fois que le rayon des coins.
(JA) 蓄電装置は、負極電極と正極電極とをセパレータを介して交互に積層してなる電極組立体と、電極組立体を収容するケース本体と、ケース本体の開口部を閉塞する蓋部材と、を備える。正極電極の底側端縁及び側端縁は、負極電極の底側端縁及び側端縁よりも内側に位置している。ケース本体の側壁の内面とケース本体の底壁の内底面との交差部にはアール状の隅部が形成されている。電極組立体の底面とケース本体の内底面との間には隙間が存在し、その隙間の深さ方向の寸法は、隅部の半径の1~1.5倍である。
