Description
図2で示した本発明の鉛蓄電池4について、表1に示したように、隔壁6のテーパーと、貫通孔6a周囲に配置した領域Aのテーパーを種々変化させた電池を作成した。また、互いに隣接しあうセル室7において、交互に電解液を注液し、セル室7間の電解液移動が確認しやすい状態とした。
実施例2では、実施例1において、セル室7内圧をすべて大気圧とした実験を行った。実施例1の各電池を新たに準備したものを供試電池とした。実施例1と同様、互いに隣接しあう2つのセル室7を一組として、組の一方のセル室7に電解液を貫通孔6a上端の位置まで注液し、もう一方のセル室7には電解液を注液しなかった。この状態で、電池を25℃中で1ヶ月間放置し、放置開始24時間後と、1ヶ月後の液リークの状態を確認した。その結果を表2に示す。

Claims (2)
- 隔壁によって複数のセル室に区画された電槽を有し、前記セル室に極板群が収納され、前記隔壁を介して隣接しあう前記極板群間を、前記極板群に設けた接続体で前記隔壁に設けた貫通孔を介して抵抗溶接した鉛蓄電池であり、前記セル室に収納した電解液面が少なくとも前記貫通孔に到達する高さにあり、前記隔壁は、前記電槽の底部から開口部にかけてその厚みが徐々に減少するようテーパーが設けられ、かつ前記隔壁の、前記貫通孔の周囲であって、かつ前記接続体に対向する部位の厚みを均一に形成した鉛蓄電池。
- 前記セル室の内圧に応じて開閉する弁を備えた請求項1に記載の鉛蓄電池。
