Abstract

본 발명은 코어-쉘 구조의 리튬 이차 전지용 전극 활물질 복합체 및 그의 제조방법에 관한 것으로, 보다 상세하게는 전극 활물질을 포함하는 코어; 및 상기 코어의 표면에 위치하고 리튬 이온 전도성 무기물을 포함하는 쉘을 포함하는 코어-쉘 구조의 리튬 이차 전지용 전극 활물질 복합체에 관한 것이다. 본 발명에 따른 전극 활물질 복합체는 용액 공정을 이용함으로써 코어의 표면이 리튬 이온 전도성 무기물을 포함하는 쉘에 의해 70% 이상 둘러 싸여지며 전해액과의 반응 안정성이 우수하고, 리튬 이온 전도성을 가져 리튬 이차 전지의 고용량화 및 장수명화를 가능하게 한다.
