Abstract:
Provided are nickel manganese composite hydroxide particles having a small and uniform particle size and having a double structure which enables to obtain a cathode active material having a hollow structure, and a manufacturing method thereof. When obtaining the nickel manganese composite hydroxide by a reaction crystallization, using an aqueous solution for nucleation, which includes at least a metallic compound that contains nickel, a metallic compound that contains manganese and an ammonium ion donor and controlling the pH value that is measured at a standard solution temperature of 25° C. is 10.5 to 12.0, nucleation is performed in an oxidizing atmosphere in which the oxygen concentration is greater than 1% by volume, and then nuclei are grown by switching the atmosphere from the oxidizing atmosphere to a mixed atmosphere of oxygen and inert gas in which the oxygen concentration is 1% by volume or less.

Claim (Index 11):
Nickel manganese composite hydroxide particles that are expressed by a general formula of NixMnyCozMt(OH)2+a (where x+y+z+t=1, 0.3\u2264x\u22640.7, 0.1\u2264y\u22640.55, 0\u2264z\u22640.4, 0\u2264t\u22640.1, 0\u2264a\u22640.5, and M is one or more added elements that are selected from among Mg, Ca, Al, Ti, V, Cr, Zr, Nb, Mo and W), and that are spherical shaped secondary particles that are formed by a plurality of aggregate primary particles, wherein the secondary particles have an average particle size of 3 to 7 \u03bcm, a value [(d90\u2212d10)/average particle size], which is an index indicating an extent of particle size distribution thereof, of 0.55 or less, and wherein the secondary particles have a center section comprising fine primary particles, and an outer shell section on the outside of the center section comprising plate shaped primary particles that are larger than the fine primary particles.
