Abstract

본 발명은 리튬화된 금속 탄소 복합체 전극의 제조 방법, 이에 의하여 제조된 리튬화된 금속 탄소 복합체 전극 및 이를 포함하는 전기화학소자에 관한 것으로, 보다 상세하게는 우수한 충방전 특성 및 사이클 특성을 가지는 새로운 구조의 리튬화된 금속 탄소 복합체 전극을 제조하는 방법, 이에 의하여 제조된 리튬화된 금속 탄소 복합체 전극 및 이를 포함하는 전기화학소자에 관한 것이다. 본 발명에 따른 리튬화된 금속 탄소 복합체 전극은 리튬이 금속과 합금을 형성하면서 동시에 탄소의 결정 구조 속에 삽입되어 안정된 구조의 복합체를 형성하기 때문에, 충방전 과정에서 금속의 부피 변화가 적어, 이에 따른 사이클 특성이 저하되지 않고 충방전 용량이 향상되며, 초기 충방전 시 비가역 용량을 제어할 수 있고, 안전성이 떨어지는 리튬 금속 음극을 대체하는 효과를 가진다.
