Abstract
Description
群は、2つの絶縁板33,35によって上下から挟まれている。正極リード16は上側の絶縁板33の貫通孔34を通って封口体23側に延び、封口体23の底板であるフィルタ24の下面に溶接されることでフィルタ24に電気的に接続される。電池10では、フィルタ24と電気的に接続された封口体23の天板であるキャップ28が正極端子となる。
次に本実施形態に係る電池10の製造方法を説明する。電池10の製造方法は、電極体収容工程とリード溶接工程とを含む。まず、電極体収容工程は、外装缶51の底部52の内面に負極リード17のU字形部18を対向させた状態で、外装缶51に電極体11を収容する。この状態で、正極リード16を外装缶51の開口部側に配置する。
