| abstract |
The present invention provides a positive electrode active material having moderate particle size and high particle size uniformity, and nickel composite hydroxide as its precursor. When obtaining a nickel composite hydroxide by a crystallization reaction, an aqueous solution for nucleation containing at least a nickel-containing metal compound and an ammonium ion donor is carried out so that the pH value at 25°C liquid temperature standard becomes 12.0 to 14.0 After nucleation is carried out under control, the aqueous solution for particle growth containing the nuclei formed above is controlled so that the pH value at 25° C. liquid temperature becomes 10.5 to 12.0 and the pH value is lower than the pH value in the nucleation step, The particles are thereby allowed to grow. At this time, at least from the start of the particle growth step to more than 40% of the total time of the particle growth step, while carrying out in a non-oxidizing environment with an oxygen concentration of 1% by volume or less, at least the The power used for stirring per unit volume in the nucleation process is controlled at 0.5-4 kW/m 3 . |
