Description
第一、角形電池ケースの本体を押出工程及び複数回の引抜工程によって製造することにより、本体の厚さを要求する厚さに製造するとともに、本体にクラックなどが発生することを防止し、不良率を減少させるとの効果がある。
前記段階(c)の後、図4aに示したように、本体100の漏洩防止溝110を加工する段階(c')をさらに含む。前記漏洩防止溝110は、本体100の開放された一端内部に加工される溝であって、切削加工などの方法により本体100の内部に加工される。
前記段階(c)の後、図5aに示したように、本体100'に接合溝110'を加工する段階(c'')をさらに含む。前記接合溝110'は、本体100'の開放された一端を外部から内部側に切削して加工するものであって、接合溝110'の一部が本体100'の外部に開口された形態に形成される。前記接合溝110'は、前述したように切削加工によって形成され得るが、必ずしもこれに限定されはしない。
