Zusammenfassung:	Disclosed are a negative electrode active material, a lithium battery adopting the same, and a preparation method thereof. The negative electrode active material comprises a composite including: a silicone-based core; an island-type metal nitride discontinuously arranged on the silicone-based core; and a nanostructure arranged on the silicone-based core or the metal oxide. A negative electrode has electric conductivity increased by comprising the negative electrode active material. Thus, a lithium battery adopting the negative electrode has improved lifespan characteristics. 음극 활물질, 이를 채용한 리튬 전지 및 이의 제조 방법이 개시된다. 상기 음극 활물질은 실리콘계 코어, 상기 실리콘계 코어 상에 불연속적으로 배치된 아일랜드 타입의 금속 질화물 및 상기 실리콘계 코어 또는 상기 금속 질화물 에 배치된 나노 구조체를 포함하는 복합체를 포함함으로써, 이를 포함하는 음극의 전기전도도가 향상될 수 있다. 이에 따라, 상기 음극을 채용한 리튬 전지의 수명 특성이 개선될 수 있다.
