  "textContent": "The present invention aims at providing a transition metal composite hydroxide, the use of which as a precursor allows a lithium transition metal composite oxide having a small and highly uniform particle diameter to be obtained. Provided is a method for producing a transition metal composite hydroxide represented by a general formula (1) MWA(OH)(wherein, x + s + t = 1, 0< s ≤ 0.05, 0 < s + t ≤ 0.15, 0 ≤ α ≤ 0.5, M is at least one transition metal selected from Ni, Co and Mn, and A is at least one additive element selected from transition metal elements other than M and W, group 2 elements, and group 13 elements), coated with a compound containing the additive element, and serving as a precursor of a positive electrode active material for nonaqueous electrolyte secondary batteries, the method comprising: a composite hydroxide particle production step including a nucleation stage of forming nuclei and a particle growth stage of growing a formed nucleus; and a coating step forming a coating material containing a metal oxide or hydroxide on the surfaces of composite hydroxide particles obtained through the upstream step.",
