Abstract
A ternary cathode material, a preparation method thereof, and a lithium ion battery are provided. The ternary cathode material comprises a micron-sized single-crystalline particle structure of LiNiCoMnMO, wherein 0.6<1-x-y-z<1.0, 0<x<0.2, 0<y<0.3, and 0<z<0.1; and the single-crystalline particle structure comprises a central area and surface layer area, wherein the molar ratio of elements in the central area meets Ni:Co:Mn:M=a1:x1:y1:z1, and the molar ratio of elements in the surface layer area meets Ni:Co:Mn:M=a2:x2:y2:z2, in which 0.85≤a1<1.0, 0<x1≤0.1, 0<y1≤0.15, 0≤z1≤0.05, 0.3≤a2≤0.7, 0.2≤x2, y2≤0.4, and 0≤z2≤0.05, provided that z1 and z2 are not simultaneously zero, and a1/(a1+x1+y1+z1)>a2/(a2+x2+y2+z2); and M comprises at least one selected from Al, Mg, Ti, Ga, Nb, Zr, W, Mo and Ta.
