摘要：
The present invention aims at providing a high-nickel positive electrode active material in which stability and initial capacity are improved and crack generation at an interface between primary particles is also suppressed, a preparation method thereof, and a positive electrode and a lithium secondary battery which include the positive electrode active material.
Also, the present invention aims at providing a high-nickel positive electrode active material in which a washing process may be omitted by reducing an amount of lithium impurities, a preparation method thereof, and a positive electrode and a lithium secondary battery which include the positive electrode active material.
