Abstract

The invention relates to a preparation method of a high nickel type ternary positive electrode material doped with rubidium elements. The method is characterized in that (1), precursor of a nickel-cobalt-manganese ternary material is prepared by a chemical co-precipitation method; and (2), the nickel-cobalt-manganese ternary material precursor is uniformly mixed with rubidium compound and lithiumsalt, and then the high nickel type ternary positive electrode material is obtained by multistage calcination. The method is advantaged in that the material structure stability is improved while relatively high energy density is kept, the ternary material doped with the rubidium elements is applied to a lithium battery, and high rate performance and discharge capacity are achieved.
