Abstract:
The present invention provides a precursor for the production of positive electrode active material for a secondary battery comprising: a core containing transition metal hydroxides comprising nickel (Ni) and manganese (Mn), or transition metal hydroxides comprising nickel (Ni), manganese (Mn) and cobalt (Co); and a shell containing transition metal hydroxides comprising cobalt (Co), and a positive electrode active material produced using the same.

Claim (Index 4):
A method for producing a precursor for the production of a positive electrode active material according to  claim 1  comprising the steps of:\n (a) preparing a transition metal aqueous solution in which a nickel salt and a manganese salt are mixed or a transition metal aqueous solution in which a nickel salt, a cobalt salt, and a manganese salt are mixed, and a sodium hydroxide aqueous solution, and an ammonia aqueous solution; \n (b) supplying the transition metal aqueous solution, the sodium hydroxide aqueous solution and the ammonia aqueous solution into a wet-type reactor, followed by mixing and reaction to obtain a spherical precipitate; and \n (c) simultaneously injecting the spherical precipitate, the aqueous solution of cobalt-based metal salt, the ammonia aqueous solution, and the sodium hydroxide aqueous solution into a wet-type reactor adjusted to have an inert atmosphere, followed by mixing and reaction to obtain a precipitate of particles having a core-shell structure.
