Abstract
In the present disclosure, the above issue is addressed by providing metal hydroxide particles used as a precursor of a positive electrode active material, in which: the metal hydroxide particles are secondary particles obtained by aggregation of a plurality of primary particles; the primary particles contain a transition metal element; and when a particle size of the primary particles at a cumulative volume of 10% from a finer side is defined as D10 [μm], the particle size at a cumulative volume of 50% is defined as D50 [μm], and the particle size at a cumulative volume of 90% is defined as D90 [μm], the primary particles satisfy 0.3≤(D90−D10)/D50.
