Abstract

본 발명은 알카리-아연 2차전지의 제조방법에 관한 것으로, 좀 더 상세하게는 아연 및 아연산화물을 활물질로 하는 아연 음전극을 가지는 알카리-아연 2차전지의 제조방법에 있어서, 아연 음전극 에지부에 해당하는 부분과 일치하는 한쪽 로울러의 양 외곽부에 돌출부가 형성된 로울러를 이용하여 아연 음전극의 에지부를 극판 중앙부보다 더 가압하여 아연 활물질을 집전체에 형성시키므로써 아연 음전극 에지부에서의 활물질 탈락 및 음전극 극판의 변형을 억제하고, 이에 따른 전지 싸이클 수명을 증진시키며, 극판 제조공정을 단순화할 수 있고 제품의 불량률을 감소시킬 수 있는 알카리-아연 2차전지의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an alkali-zinc secondary battery, and more particularly, in a method for manufacturing an alkali-zinc secondary battery having a zinc negative electrode using zinc and zinc oxide as an active material, at a zinc negative electrode edge portion. The active material is dropped from the edge of the zinc negative electrode and the negative electrode is formed by pressing the edge of the zinc negative electrode more than the center of the electrode plate using a roller having protrusions formed at both outer edges of one roller corresponding to the corresponding portion to form a zinc active material in the current collector. The present invention relates to a method for manufacturing an alkali-zinc secondary battery that can suppress deformation of the electrode plate, thereby improving battery cycle life, simplify the electrode plate manufacturing process, and reduce the defective rate of the product.
