Claims (3)
- 複数の電槽が隔壁を介して連接され、正極板と負極板をセパレータを介して積層した極板群とその両側に接合された正負の集電板からなる発電要素が各電槽に収容され、隣接する電槽の隔壁両側の集電板同士が接続された二次電池において、隔壁の複数箇所に貫通穴を設け、集電板に各貫通穴に嵌入して先端同士が当接する複数の接続突部を突出形成し、極板群の両側に突出された各極板のリード部における、集電板の接続突部に対応する部位に溶接作業用の切欠部を設け、電槽両側壁の隔壁隣接部におけるリード部の切欠部に対応する部位に溶接作業用の開口を設け、前記開口と前記切欠部とを、前記開口と前記切欠部とを通して溶接電極が前記電槽を貫通できるように設け、接続突部同士を溶接したことを特徴とする二次電池。
- 集電板における各極板のリード部に対向する部分に複数の接続突部を配設したことを特徴とする請求項1記載の二次電池。
- 正極板と負極板をセパレータを介して積層した極板群を作成する工程と、複数の接続突部を突出成形された集電板を極板群の両側に接合して発電要素を作成する工程と、複数箇所に貫通穴が形成されている隔壁を介して連接されている複数の電槽に発電要素を収容して集電板に突出形成されている接続突部を貫通穴に嵌入させる工程と、接続突部の先端同士を溶接する溶接工程とを有することを特徴とする二次電池の製造方法であって、
前記溶接工程は、溶接電極を、電槽両側壁の隔壁隣接部に形成された開口と極板群両側の各極板のリード部に形成された切欠部を通して電槽を貫通させ、前記溶接電極を両端支持した状態で押圧して行うことを特徴とする二次電池の製造方法。
