Abstract

본 발명은 메쉬 형태의 절연층을 포함하는 리튬 이차전지용 음극 및 이를 포함하는 리튬 이차전지에 관한 것으로, 보다 상세하게는 상기 리튬 금속층의 일면 상에 형성되며 공극을 가지는 메쉬 형태의 절연층을 포함하는 리튬 이차전지용 음극 및 이를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따른 음극을 적용한 리튬 이차전지는 리튬 덴드라이트의 석출 및 제거 반응을 상기 절연층의 공극 내부에서 유도하여, 리튬 금속 표면상에 리튬 덴드라이트의 국소적인 형성을 억제하고 균일한 표면을 형성하게 하며 셀의 부피팽창을 억제할 수 있고, 초기 형성된 부동태막에 지지층을 형성하여 부동태막의 탈리 및 붕괴를 막아 전해액과의 추가적인 부반응을 억제함과 동시에 Dead lithium 을 최소화하여 전지의 수명 특성을 높일 수 있다.
