使用金属板制造棱形蓄电池组电池之方法;METHOD OF MANUFACTURING PRISMATIC BATTERY CELL USING METAL PLATE

摘要

揭示一种制造密封于棱形蓄电池组之匣内的蓄电池组电池之方法，其含有一包括阴极、阳极和在该阴极与该阳极之间所设置之间隔件的电极组合件。该方法包括(a)弯曲而后熔接具有预定厚度之金属板以制造具有开放的上部和底部的棱形物体；(b)制造上部和底部密封构件，其分别对应于该棱形物体之上部和底部的形状；(c)使该底部密封构件与该棱形物体之底部接触而后熔接；(d)将该电极组合件设置于依照该接触而后熔接所制造之具有经密封之底部的蓄电池组之匣中；及(e)使依照步骤(d)所制造之该蓄电池组之匣的上部与该上部密封构件接触而后熔接。; (b) manufacturing an upper and bottom portion sealing member corresponding to shape of each of the upper portion and the bottom portion of the prismatic body; (c) contacting and then welding the bottom portion of the prismatic body with the bottom portion sealing member; (d) inserting the electrode assembly into the battery case, the bottom portion of which is sealed, manufactured according to step (c); and (e) contacting and then welding the upper portion of the battery case manufactured according to step (d) with the upper portion sealing member.
