Provided is an electrode active material, which contains at least two different active materials of a primary particle state, maximizes the advantages of the respective active materials, and is prepared to correspond with the goal of a desired battery. The electrode active material is an electrode active material of a secondary particle state formed by putting active materials of a primary particle state together. The secondary particle comprises at least two different active materials of the primary particle state. The electrode active material is prepared by the steps of: mixing at least two active materials of the primary particle state with a solvent to form slurry; and subjecting the slurry to granulation to form granules of the secondary particle state. |
