Preparation method for nickel cobalt lithium manganate LiNixConMn1-x-yO2 of anode material of lithium ion battery

The invention discloses a preparation method for nickel cobalt lithium manganate LiNixConMn1-x-yO2 of an anode material of a lithium ion battery, which belongs to the technical field of a novel material for energy source. The preparation method comprises the following steps of: 1, dissolving lithium source compound, nickel source compound, cobalt source compound and manganese source compound in deion water, adding complexant polyacrylic acid (PAA), and heating and stirring to obtain transparent red collosol; 2, heating and concentrating, evaporating unnecessary water to obtain red wet gel, and drying in a bake oven to obtain dried gel; and 3, carrying out calcination and heat treatment for ground dried gel in a muffle furnace to obtain powders of nickel cobalt lithium manganate LiNixConMn1-x-yO2. The method provided by the invention has the advantages of simple process, environment-protection, low energy consumption high efficiency and the like.
