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 15):
A manufacturing method for manufacturing a cathode active material for a non-aqueous electrolyte secondary battery comprising lithium nickel manganese composite oxide having a layered hexagonal crystal structure and expressed by a general formula of Li1+uNixMnyCozMtO2 (where \u22120.05\u2264u\u22640.50, x+y+z+t=1, 0.3\u2264x\u22640.7, 0.1\u2264y\u22640.55, 0\u2264z\u22640.4, 0\u2264t\u22640.1, M is one or more added elements that are selected from among Mg, Ca, Al, Ti, V, Cr, Zr, Nb, Mo and W),\n the manufacturing method comprising: heat treatment of the nickel manganese composite hydroxide particles of any one of the  claims 11  to  14  at a temperature of 105 to 750\u00b0 C., a mixing step that mixes a lithium compound into the heat treated particles to form a lithium mixture; and a calcination step that performs calcination of the mixture formed in the mixing step in an oxidizing atmosphere at a temperature of 800 to 980\u00b0 C.
