A method for preparing nickel hydroxide is provided, in which a nickel sulfate solution and ammonium hydroxide are continuously mixed in a premixing vessel to form a nickel ammonium complex, and then the mixed solution and a sodium hydroxide solution are continuously supplied to a reactor. Included in the method of producing nickel hydroxide is the step of adding more than one element selected from the group consisting of Co, Zn and Cd to the nickel sulfate solution in a concentration range of 0.05-0.3 mol/L. The high density nickel hydroxide may be used for alkali rechargeable batteries. |
