Abstract
【解決手段】 電池ケースおよび該電池ケースの開口部を封口する蓋板にアルミニウムを用いてなる角形密閉式蓄電池において、上記蓋板または電池ケースに形設された電解液注入用の注入孔から電池内に電解液を注入した後、上記注入孔に、上部の平面形状が円形であり、かつ軸部の長さが蓋板の厚みより大きい封止栓を挿入し、レーザー溶接により上記封止栓を蓋板または電池ケースと一体化して上記注入孔を気密封止する。
上記溶接条件は出力50W〜300W、レーザービーム径0.3mm〜1mm、移動速度1mm/秒〜15mm/秒が好ましい。
【選択図】 図1
Description
図1はこの実施例1の角形密閉式蓄電池を概略的に示すもので、図1の(a)はその平面図で、(b)はその断面図である。
実施例1と同様の電池の蓋板に、直径1mmの注入孔を設け、該注入孔から電解液を注入した後、該注入孔に直径1.2mmの球状の封止栓を置き、その上部に超音波ホーンを当てがって、振動数20kHz、振幅30μm、荷重60kgfの条件下で超音波振動を付加し、封止栓を蓋板に溶接した。
