Description
図1は電池1の一例を示す。電池1は、電極群2と、電極群2が収納される外装容器3と、を備える。外装容器3は、アルミニウム、アルミニウム合金、鉄又はステンレス等の金属から形成される。外装容器3は、容器本体5と、蓋6と、を備える。ここで、電池1及び外装容器3では、縦方向(矢印X1及び矢印X2で示す方向)、縦方向に対して交差する(垂直又は略垂直な)横方向(矢印Y1及び矢印Y2で示す方向)、及び、縦方向及び横方向の両方に対して交差する(垂直又は略垂直な)高さ方向(矢印Z1及び矢印Z2で示す方向)が、規定される。電池1及び外装容器3のそれぞれでは、縦方向についての寸法が、横方向についての寸法、及び、高さ方向についての寸法のそれぞれに比べて、遥かに小さい。
図6に示す変形例では、板部26に開口部29が形成されておらず、板部31にのみ開口部29が形成されている。この場合、板部26において接合部25を形成可能な領域が広くなる。よって、集電タブ(15B及び16Bの対応する一方)にクリップ板21を接合する場合、集電タブにクリップ板21を容易に接合できる。
