More Information
Summary:Provided is a nickel composite hydroxide that was excellent in reactivity to a lithium compound and a positive electrode active material using the nickel composite hydroxide as a precursor. The nickel composite hydroxide, having an average diameter of pores of 50 Å or larger and 60 Å or smaller in pore distribution measurement by a nitrogen adsorption method and an integrated intensity ratio of a diffraction peak appearing in a range of 2θ = 51.9 ± 1.0°/a diffraction peak appearing in a range of 2θ = 19.1 ± 1.0° in powder X-ray diffraction using CuKα rays of 0.40 or more and 0.50 or less.
