摘要：
The present invention provides a positive electrode active material precursor for a lithium secondary battery, in which the positive electrode active material precursor is represented by the following composition formula (I), a ratio (α/β) between a half width α of a peak that is present within a range of a diffraction angle 2θ = 19.2 ± 1° and a half width β of a peak that is present within a range of 2θ = 38.5 ± 1° is equal to or greater than 0.9 in powder X-ray diffraction measurement using a CuKα beam:
