Abstract:
A manganese nickel composite hydroxide which serves as a starting material for positive electrode active materials for secondary batteries, and the secondary battery having low resistance and high output characteristics. A manganese nickel composite hydroxide according to the present invention is represented by general formula (A) Mn 1−x−y Ni x M y (OH) 2+α  (wherein 0≤×≤0.27, 0≤y≤0.05, 0≤α≤0.5, and M represents at least one element selected from among Mg, Al, Ca, Ba, Sr, Ti, V, Fe, Cr, Co, Cu, Zr, Nb, Mo and W), and has an SO 4  content of 0.90% by weight or less, an Na content of 0.04% by weight or less, a BET specific surface area of from 40 m 2 /g to 70 m 2 /g (inclusive), and a value obtained by [(d 90  -d 10 )/(average particle diameter)] of 0.90 or less, said value being an index indicating the expanse of the particle size distribution.

Claim (Index 1):
Manganese-nickel complex hydroxide represented by general formula (A): Mn 1\u2212x\u2212y Ni x M y (OH) 2+\u03b1  (0\u2264x\u22640.27, 0\u2264y\u22640.05, 0\u2264\u03b1\u22640.5, and M is at least one element selected from among Mg, Al, Ca, Ba, Sr, Ti, V, Fe, Cr, Co, Cu, Zr, Nb, Mo, and W), wherein\n a SO 4  content is 0.90% by weight or less and a Na content is 0.04% by weight or less, \n a BET specific surface area is 40 m 2 /g or more and 70 m 2 /g or less, and \n a value which is an index indicating the expanse of particle size distribution and is determined by [(d 90 -d 10 )/average particle diameter] is 0.90 or less.
