Abstract

본 발명은 음극부체 리튬 분말을 사용함으로서 리튬 메탈 전극의 문제인 덴드라이트(dendrite)성장을 억제하고, 젤-고분자 전해질(gel-polymer electrolyte)을 사용함으로서 전지반응에 참여하는 전극의 유효표면적을 증대시킴과 동시에 덴드라이트 성장을 한층 더 억제하도록 하여 안전성에 기여할 수 있도록 하였고, 기존의 리튬계 양극(lithiated cathode) 대신 비-리튬계 양극(non-lithiated cathode)을 사용함으로서 고용량 장수명화를 가능하게 하는 리튬 이차 전지 및 그 전극 제조 방법에 관한 것이다. 상기 젤-고분자 전해질은 주입 상태에서는 기공이 존재하는 리튬분말전극에 깊숙이 스며들어 전극 표면뿐만 아니라, 내부의 리튬분말도 전지반응에 참여하도록 유도할 수 있으며, 젤화 후에는 분말을 단단히 감싸줌으로써 덴드라이트의 성장을 억제할 수 있다. 이를 통해 종래에 문제시되었던 리튬 메탈 전극의 안전성과 수명안정성에 대한 문제를 극복할 수 있다.
