Abstract
A method for producing a nickel-containing hydroxide is provided that includes a particle growth step of promoting growth of nickel-containing hydroxide particles by neutralization crystallization in an aqueous solution accommodated in an agitation tank. In the particle growth step, an averaged value of the maximum accelerations of the flows of streamlines for the aqueous solution is greater than 600 m/s.
