Abstract: Provided is a positive electrode active material which includes an inner region that is a region from the center of the positive electrode active material particle to R/2, and an outer region that is a region from R/2 to the surface of the positive electrode active material particle, wherein R is a distance from the center of the positive electrode active material particle to the surface thereof. The positive electrode active material further includes 25% to 80% of crystallites C with respect to a total number of crystallites in the outer region. The crystallites C have a high crystallite long-axis orientation degree of 0.5 to 1 and a low crystallite c-axis orientation degree less than 0.5. Thus, the positive electrode active material has high capacity characteristics and a small amount of gas generated.

Abstract: Provided is a positive electrode active material including a plurality of crystallites A, wherein the plurality of crystallites A has a crystallite long-axis orientation degree DoA represented by Equation 1 below is 0.5 to 1, and a crystallite c-axis orientation degree represented by a cross product value of a c-axis rotation vector Rc of a crystal lattice of a crystallite obtained by electron backscatter diffraction (EBSD) analysis and a position unit vector P? of the crystallite is 0.5 to 1. A proportion of the plurality of crystallites A is 25% to 80% with respect to a total number of crystallites in a cross-section of a positive electrode active material. Further provided is a positive electrode and a lithium secondary battery including the positive electrode active material.

Abstract: Provided is a positive electrode active material which includes an inner region that is a region from the center of the positive electrode active material particle to R/2; and an outer region that is a region from R/2 to the surface of the positive electrode active material particle, wherein R is a distance from the center of the positive electrode active material particle to the surface thereof. The positive electrode active material further includes 30% to 80% of crystallites A with respect to a total number of crystallites in the outer region of the positive electrode active material, the crystallites A having high crystallite long-axis orientation degree and crystallite c-axis orientation degree. Thus, the positive electrode active material can achieve excellent capacity characteristics and service life characteristics.
