Abstract

리튬 이차전지용 음극 활물질, 그 제조방법 및 이를 포함하는 리튬 이차전지가 제공된다. 본 발명에 따른 리튬 이차전지용 음극 활물질은 리튬 이온이 흡수/방출될 수 있는 활성 입자; 및 상기 활성 입자 표면에 코팅된 코팅층을 포함하며, 여기에서 상기 코팅층은 나노 중공 섬유인 제 1 물질과 탄소전구체 또는 LTO인 제 2 물질을 포함하는 것을 특징으로 하며, 본 발명의 리튬 이차전지용 음극 활물질은 실리콘의 경우 충/방전시 리튬과의 반응에 의한 체적 변화로 균열이 발생하고 활물질 입자가 파괴됨으로 충/방전 사이클 진행됨에 따라 용량이 급격하게 저하되는 현상을 방지하며, 이로써 사이클 수명이 길어지므로, 고용량 전지에 적합한 고에너지 밀도를 확보할 수 있다.
