摘要： A positive electrode additive for a lithium secondary battery can improve atmospheric stability. A method of manufacturing the same and a positive electrode for a lithium secondary battery includes the same. The positive electrode additive for a lithium secondary battery is used to manufacture the positive electrode for a lithium secondary battery and includes a lithium (Li)-based additive core and a coating layer of NbOXCy (0≤x≤2.5 and 0≤y≤1; where Nb=niobium, O=oxygen, C=carbon) formed on a surface of the additive core.
