Abstract

전지관 내면에 표면거치름이나 균열을 발생시킴과 동시에, 전지관 외면은 거울면으로 한다. 합금도금 강판으로 이루어지며, 그 강판의 양면의 도금층의 경도를 다르게하여 전지관 형성시에 경도가 높은 도금층은 전지관 내면에 경도가 낮은 도금층은 전지관 외면이 되도록 사용한다. 상기 합금도금으로서 니켈합금도금을 사용하고, 니켈이외의 금속량 또는 금속이 종류, 유기물의 첨가의 유무, 그 첨가량을 다르게하여 도금층의 경도를 다르게 하고 있다. 이 합금도금 강판을 트랜스퍼 조르기, DI 조르기등의 프레스조르기 방법으로 전지관을 만들어, 경도가 높은 합금도금을 한 전지관 내면에 표면거치름과 균열을 발생시키고 있다.
