<p>PROBLEM TO BE SOLVED: To provide a nickel hydroxide production method capable of suppressing aggregation of primary particles of nickel hydroxide which are obtained, reducing density of impurity, and preventing scale adhesion due to the nickel hydroxide generated on an anode surface and cathode surface, for suppressing increase of electrolytic voltage, when the nickel hydroxide is produced by an electrolytic method.SOLUTION: Provided is the nickel hydroxide production method in which an electrolyte of ammonium nitrate and ammonium halide as an electrolyte is electrolyzed under ultrasonic atmosphere, for obtaining nickel hydroxide having a value of grain size distribution D50 is 1μm or less, and density of impurity is low, with high yield with respect to an electric amount used for conduction.</p> |
