Abstract

Disclosed are an aluminum-coated precursor and a preparation method therefor. The aluminum coated precursor has a chemical formula of xMCO(1-x)·Al(OH), wherein M is at least one of nickel, cobalt and manganese, and x is 0.995-0.999. The aluminum-coated precursor has the advantages of a controllable particle size and uniform particle size distribution, a high degree of sphericity, a smooth particle surface, a high tap density, not easily breaking, and an excellent electrochemical performance and energy density.
