description The invention relates to methods for preparing a nickel-cobalt-aluminum precursor material and a nickel-cobalt-aluminum cathode material with gradient distribution of the aluminum element. The precursor material and the cathode material based on the precursor prepared according to the methods are of sphere or spherelike shapes in which the distribution of the aluminum element is changed in a gradient manner, and particle sizes are uniformly distributed. The synthesized material is high in tap density and specific capacity, is not sensitive to ambient carbon dioxide and moisture, and has high machining characteristics and high stability.
