Abstract

본 발명은 강철 기판 및 그 기판 상부에 니켈과 니켈 합금중에서 선택된 물질로 이루어진 제1코팅층과 제2코팅층을 포함하여 이루어진 전지의 집전체 및 그 제조방법을 개시한다. 본 발명에 따르면, 활물질의 탈락률이 감소되고 이용률이 증가된 전지를 얻을 수 있다.

Description

전지의 집전체 및 그 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 통상적인 전지의 집전체를 도시한 도면이고, 제2A도, 제2B도 및 제2C도는 본 발명에 따른 전지의 집전체 제조방법의 각 단계를 개략적으로 나타낸 단면도이다.

Claims (6)
