Abstract

본 발명은 리튬 전이금속 산화물 입자; 및 복합 입자를 포함하고, 상기 복합 입자는 YSZ(yttria stabilized zirconia), GDC(gadolinia-doped ceria), LSGM(lanthanum strontium gallate magnesite), LSM(lanthanum strontium manganite) 및 Ni-YSZ로 이루어진 군으로부터 선택되는 어느 하나 또는 이들 중 2종 이상의 혼합물을 포함하며, 상기 양극 활물질은 X-레이 회절 (X-Ray Diffraction; XRD) 분석 측정시 단일상 피크의 복합 입자를 갖는 것을 특징으로 하는 양극 활물질을 제공한다. 본 발명의 일 실시예에 따른 양극 활물질은 이차전지의 용량 감소나 출력 감소를 최소화할 수 있을 뿐만 아니라, 수명 특성을 더욱 향상시킬 수 있다.
