Abstract
A ternary positive electrode material, a method for preparing the same, a positive electrode sheet and a lithium ion battery in which the ternary positive electrode material has a chemical composition of Li(NiCoM)M'OA, wherein 0.75≤a≤1.2, 0.5≤x<1, 0<y≤0.1, 0≤b≤0.01, 0≤c≤0.2; M is at least one selected from the group consisting of Mn and Al; M′ is at least one selected from the group consisting of Al, Zr, Ti, Y, Sr, W and Mg; A is at least one selected from the group consisting of S, F and N; and 2%≤C−C, 5%≤C−C. The lithium ion battery shows better short-term kinetic performances and long-term kinetic performances, and it also exhibits excellent stability in long-term cycles.
