Abstract

본 발명은 리튬 금속층, 상기 리튬 금속층의 적어도 일면에 형성되며 질화리튬 박막층 및 상기 질화리튬 박막층 상에 형성되는 탄소계 박막층을 포함하는 음극, 이의 제조방법 및 이를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따르면, 리튬 금속층 상에 형성된 질화리튬 박막층 및 탄소계 박막층은 음극의 비표면적을 늘려줄 뿐만 아니라, 리튬 금속층과 전해질의 직접적인 접촉에 의한 부반응을 차단하여 전류밀도 분포를 균일하게 구현하고, 리튬 덴드라이트 형성을 억제함으로써, 사이클 성능을 향상시키고 과전압을 감소시켜 리튬 이차전지의 전기화학 성능을 개선시킨다.
