description The present invention relates to a positive electrode active material coated with a coating layer capable of improving the surface stability of the positive electrode active material by preventing side reactions between an electrolyte and the positive electrode active material, and specifically, to a positive electrode active material coated with a coating layer including at least one compound selected from compounds represented by chemical formulas I to III described in the specification, a method for manufacturing the same, a positive electrode including the same, and a lithium secondary battery. 본 발명은 전해액과 양극 활물질 간의 부반응을 방지하여 양극 활물질의 표면 안정성을 향상시킬 수 있는 코팅층으로 코팅된 양극 활물질에 관한 발명으로, 본 명세서에 기재된 화학식 I 내지 화학식 III으로 표시되는 화합물 중에서 선택되는 1종 이상의 화합물을 포함하는 코팅층으로 코팅된 양극 활물질, 이의 제조방법 및 이를 포함하는 양극 및 리튬 이차전지에 관한 것이다.
