Abstract

본 발명은 하기 [화학식 1]로 표시되는 리튬 망간산화물과 2.5 V 내지 3.3V에서 평탄준위 전압 프로파일(profile)을 갖는 화학양론 스피넬 구조의 Li4Mn5O12를 포함하는 혼합 양극활물질 및 이를 포함하는 리튬이차전지에 관한 것이다. [화학식 1] xLi2MnO3 · (1-x)LiMO2 상기 [화학식 1]에서, 0<x<1이고, M은 Al, Mg, Mn, Ni, Co, Cr, V 및 Fe로 이루어진 군에서 선택되는 어느 하나의 원소, 또는 2 이상의 원소가 동시에 적용된 것이다. 상기 혼합 양극재는 및 이를 포함하는 리튬이차전지는 향상된 안전성을 가짐과 동시에 저SOC 구간에서의 낮은 출력을 상기 Li4Mn5O12이 보완하여 요구출력 이상으로 출력을 유지함으로써 가용 SOC 구간을 넓힐 수 있는 혼합 양극활물질 및 이를 포함하는 리튬이차전지를 제공하여, PHEV 또는 EV 등에 적합하게 사용될 수 있다.
