Claims (5)
- 幅の狭い短側面と幅の広い長側面とを有する直方体状の電槽内に、その長側面と平行な多数の正極板と負極板をセパレータを介して短側面方向に積層した極板群を収納して成る単電池が連結された集合型二次電池において、
前記単電池は、
正極板と負極板の互いに反対側の側縁部を両極板の対向部分から外側に突出させ、突出部をリード部とし、
極板群の正負それぞれのリード部の側端縁を集電板に固着し、集電板にて極板群を保持し、
前記集合型二次電池は、複数の電槽をその短側面で相互に一体的に連結して成る一体電槽を設け、電槽間の短側面を貫通する接続金具で両側の集電板を接続したことを特徴とする集合型二次電池。 - 集電板の上端において、他の極板群または外部端子と接続されたことを特徴とする請求項1記載の集合型二次電池。
- 電槽間の短側面に接続穴を貫通形成し、接続金具は、接続穴に挿入されてその先端同士が溶接される突出軸部を有するとともに基端面に集電板が固着される一対のコマ金具にて構成したことを特徴とする請求項1または2記載の集合型二次電池。
- 単電池が連結された集合型二次電池において、
幅の狭い短側面と幅の広い長側面とを有する直方体状の電槽内に、その長側面方向両端に正極と負極の集電板を有する極板群と電解液を収容して単電池を構成し、電槽の短側面の上端部に接続穴を貫通形成し、接続穴に挿入される突出軸部を有するとともに基端面に集電板が固着される一対のコマ金具、または同様の突出軸部を有する接続端子とコマ金具を短側面の両側に配置してそれらの突出軸部の先端同士を溶接したことを特徴とする集合型二次電池。 - 短側面の両側に配設されたコマ金具又は接続端子の突出軸部の周囲にそれぞれ短側面との間のシールを行うシール材を配設したことを特徴とする請求項3又は4記載の集合型二次電池。
