<p>PROBLEM TO BE SOLVED: To provide nickel-containing hydroxide and nickel-containing oxide which is a monodisperse primary particle used for producing lithium composite nickel oxide which is a monodisperse primary particle having an average particle diameter of 3μm or less used for a cathode active material for a lithium ion secondary battery, and to provide methods of producing the nickel-containing hydroxide and nickel-containing oxide.SOLUTION: There is provided the nickel-containing hydroxide which is a monodisperse primary particle represented by the general formula (1):NiM(OH)( M represents at least one or more elements of Co and Al in the formula), and has an average particle diameter measured by a dynamic light scattering method of 3μm or less. There is also provided the nickel-containing oxide which is obtained by roasting the nickel-containing hydroxide at 300 to 900°C and is a monodispersed primary particle represented by the general formula (2):NiMO ( M represents at least one or more element of Co and Al in the formula), and has an average particle diameter measured by a dynamic light scattering method of 3μm or less.</p> |
