Abstract

본 발명은 음극 활물질, 그를 갖는 비수계 리튬이차전지 및 그의 제조 방법에 관한 것으로, 탄소계 재료의 표면에 MoP 와 MoP2 로 구성된 MoPx 입자를 포함하는 비정질탄소 코팅층을 형성함으로써 탄소계 소재 표면에서 리튬 이온의 삽입 시 저항을 감소시키고 표면의 반응성 및 구조적 안정성을 향상시켜 비수계 리튬이차전지의 음극 활물질로 적용 시 충방전 효율 및 수명 특성의 열화 없이 고율 충전 특성을 향상시키기 위한 것이다. 본 발명에 따른 음극 활물질은 탄소계 재료와, 상기 탄소계 재료의 표면에 형성된 MoP 와 MoP2 로 구성된 MoPx 입자를 포함하는 비정질탄소 코팅층을 포함한다. 이때 코팅층은 MoP 와 MoP2 로 구성된 MoPx 입자가 분산된 콜타르피치의 열처리를 통하여 탄소계 소재 표면에 도입할 수 있다.
