Abstract
A lithium battery positive active material precursor, a preparation method therefor and the use thereof are provided. The precursor has a chemical formula of NiCoM(OH), wherein M is at least one metal selected from the group consisting of Fe, Cr, Cu, Ti, Mg, W, Mo, Nb, Zn, Sn, Zr, Ga, Mn and Al, 0.3≤x≤1, 0<y≤0.5, 0<z≤0.3; and the precursor comprises aggregates of platy monocrystals and polyhedral monocrystal particles. In the XRD pattern of the precursor, (001), I(100) and I(101) satisfy the following relationship: I(001)/I(100) is not less than about 1.5, and I(001)/I(101) is not less than about 1.2.
