Title: Positive electrode active material and lithium secondary battery including the same
Inventor: CHUN YU GYEONG
IPC: H01M4/525
Filed: 2022-10-26
Abstract: To provide a positive electrode active material configured to improve the stability of particles by mitigating or preventing generation of cracks, a collapse of a crystal structure, and/or a change in crystal structure (phase transition) not only in the surface portions but also in the central portions of a first lithium composite oxide and a second lithium composite oxide.SOLUTION: A first lithium composite oxide and a second lithium composite oxide include at least nickel and cobalt, and the cobalt in the first lithium composite oxide and the second lithium composite oxide has a concentration gradient that decreases from a surface portion toward a central portion. When s1 represents an absolute value of a slope of the concentration gradient of the cobalt decreasing from the surface portion toward the central portion of the first lithium composite oxide and s2 represents an absolute value of a slope of the concentration gradient of the cobalt decreasing from the surface portion toward the central portion of the second lithium composite oxide, s1 and s2 may satisfy s1<s2.SELECTED DRAWING: None
