In one embodiment, the solution of the nickel salts, cobalt salts and manganese salts, the solution of precipitants and the solution of complexing agents are continuously fed into the reaction system, respectively, wherein the nickel salts, cobalt salts and manganese salts are in a molar ratio of x:y:z, wherein x, y and z are as defined above. The co-deposing may be operated under conditions of, for example, a temperature of 50-90° C., preferably 60-80° C.; a pH of 9-13, preferably 10-12, and the solution of complexing agents in a concentration of 2-8 g/L. The feed rates for the solution of the nickel salts, cobalt salts and manganese salts, the solution of precipitants and the solution of complexing agents may be selected in a wide range, as long as the feed rates may meet the requirements of maintaining pH of the reaction system within the predetermined range. Preferably, the co-deposing may be operated under stirring. Preferably, the stirring speed is about 100-1000 r/min, and preferably about 400-800 r/min; for example, 100 r/min, 200 r/min, 300 r/min, 400 r/min, 500 r/min, 600 r/min, 700 r/min or 800 r/min.

The product of the co-deposing may be subjected to aging, separating, washing and drying, to obtain the precursor of the nickel cobalt manganese active materials. Relating operations can be carried out in any conventional manner in the art.

The precursor of the nickel cobalt manganese active materials obtained in the step of co-deposing may be subjected to doping and lithiating, comprising mixing the precursor of the nickel cobalt manganese active materials with a lithium source, a first dopant containing a first dopant element, a second dopant containing a second dopant element, and a third dopant containing a third dopant element; and subjecting to programmed calcining.
