| description | The present invention relates to a lithium composite oxide capable of improving the capacity characteristics and lifespan characteristics of a lithium secondary battery, and a lithium secondary battery including the same. According to the present invention, the atomic ratio of boron (B) and nickel (Ni) in the surface of the lithium composite oxide including primary particles capable of occluding and releasing lithium and secondary particles in which the primary particles are aggregated is within a specific range to improve the stability of the lithium composite oxide, thereby improving the capacity characteristics and lifespan characteristics of the lithium secondary battery using the lithium composite oxide as a positive electrode active material.
본 발명은 리튬 이차전지의 용량 특성 및 수명 특성을 향상시키는 것이 가능한 리튬 복합 산화물 및 이를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따르면, 리튬의 흡장 및 방출이 가능한 1차 입자 및 상기 1차 입자가 응집된 2차 입자를 포함하는 리튬 복합 산화물의 표면부 내 보론(B)과 니켈(Ni)의 원자비가 특정 범위 내에 존재함으로써 리튬 복합 산화물의 안정성을 향상시킬 수 있으며, 이에 따라 상기 리튬 복합 산화물을 양극 활물질로서 사용한 리튬 이차전지의 용량 특성 및 수명 특성을 향상시키는 것이 가능하다. |
