Abstract

본 발명은 축전지용 양극판 및 그 제조 방법에 관한 것으로서, 리드편과 니켈다공체와의 접촉면적 및 용접면적을 크게하기 위하여, 활물질이 충전되어 있는 충전부와 상기 활물질이 충전되어 있지 않은 무충전부로 이루어진 다공체금속과; 상기 무충전부에 용접되며, 그 상부에 상기 무충전부와의 접촉면적을 넓히는 오목부가 형성된 리드편 : 을 구비한다.The present invention relates to a positive electrode plate for a battery and a method of manufacturing the same, and more particularly, to a positive electrode plate for a battery and a porous body made of a charger portion filled with an active material and a non- Metal and; And a lead piece, which is welded to the non-charged portion and has a concave portion on the upper portion thereof to widen the contact area with the no-charged portion.

상기 양극판을 제조하기 위하여, 다공체금속에 올려진 리드편을 펀치로 가압하여 상기 리드편과 상기 다공체 사이의 접촉면적을 넓히는 오목부를 형성하는 단계; 상기 오목부에 레이저빔을 조사하여 상기 리브편이 상기 다공체금속에 용접되도록 하는 단계;를 포함한다.Forming a concave portion for widening a contact area between the lead piece and the porous body by punching the lead piece placed on the porous metal to manufacture the positive electrode plate; And irradiating the concave portion with a laser beam so that the rib piece is welded to the porous metal.

상기와 같은 방법을 채용함으로써, 니켈다공체와 리드편 사이의 접촉면적 및 용접면적이 넓어져, 용접의 신뢰성 향상 및 전류의 통전 효율이 상승된다.By employing the above-described method, the contact area and the welded area between the nickel porous body and the lead piece are widened, thereby improving the reliability of the welding and increasing the current conduction efficiency.
