Abstract

간단하게 능률 좋고, 하이레이트 방전 특성과 사이클 특성에 우수한 전지를 제공한다.
전지의 제조 방법은 양극판(2A)가 음극판(2B) 사이에 고분자 미세 다공막의 걱리판(2C)을 사이에 끼워 원형 내지 타원형으로 감아서 통형상 전극체로 하고, 통형상 전극체를 양측에서 프레스하여 비원형 스파이럴 전극체(2)로서, 외장 용기(1)에 넣어서 전지로 한다. 통형상 전극체를 프레스하여 비원형 스파이럴 전극체(2) 로 할 때, 통형상 전극체의 격리판(2C)의 공기 투과도를 100%로 하여, 프레스된 비원형 스파이럴 전극체(2)의 격리판(2C)의 공기 투과도를 110~150%의 범위로 한다.

Description

비원형의 스파이럴 전극체를 내장하는 전지의 제조 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제4도는 본 발명의 방법으로 제조된 전지의 격리판 공기 투과도를 변경하면 하이레이트 방전 특성이 향상되는 비율을 도시하는 그래프, 제5도는 본 발명의 방법으로 제조된 전지의 격리판 공기 투과도를 변경하면 300사이클 충방전 후에 용량이 증가하는 비율을 도시하는 그래프, 제6도는 본 발명의 방법으로 제조된 전지를 도시하는 단면도.
