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 5):
A method for manufacturing manganese-nickel hydroxide, the method comprising:\n mixing a solution containing sulfate salts to be used as a manganese source and a nickel source and an alkali mixed aqueous solution which contains sodium hydroxide and sodium carbonate, is obtained by adding sodium carbonate to a sodium hydroxide solution so that a ratio of the number of moles of sodium derived from sodium carbonate to the number of moles of entire sodium is 20% or less, and is used as an alkali aqueous solution; and depositing a hydroxide by reactive crystallization.
