摘要

General formula Ni x Co y Mn z M t CO 3 (where x + y + z + t = 1, 0.05 ≦ x ≦ 0.3, 0.1 ≦ y ≦ 0.4, 0.55 ≦ z ≦ 0 .8, 0 ≦ t ≦ 0.1, and M is one or more additive elements selected from Mg, Ca, Al, Ti, V, Cr, Zr, Nb, Mo, and W). A nickel cobalt manganese carbonate composite represented, A functional group containing hydrogen, H / Me, which is a mass ratio of the contained hydrogen and the contained metal component Me, is less than 1.60, Provided is a positive electrode active material precursor for a non-aqueous electrolyte secondary battery including secondary particles formed by aggregation of a plurality of primary particles.
