Positive electrode active material for lithium secondary battery, positive electrode including the same, and lithium secondary battery including the same

Abstract

To provide a positive electrode active material with high energy density, high operation voltage, and high conductivity.SOLUTION: The present invention relates to a positive electrode active material for a lithium secondary battery, a manufacturing method for the same, and a lithium secondary battery including the same. More specifically, the positive electrode active material includes first particles containing a compound of Chemical Formula 1 and having a first average particle diameter, and second particles containing a compound of Chemical Formula 2 and having a second average particle diameter that is smaller than the first average particle diameter. The content of the second particles is greater than or equal to the content of the first particles.SELECTED DRAWING: Figure 6
