Abstract

The present invention provides a precursor for the production of a positive electrode active material for a secondary battery comprising: a core composed of transition metal hydroxides including nickel(Ni) and manganese(Mn) and further including anions other than hydroxyl groups(OH), or transition metal hydroxides including nickel(Ni), manganese(Mn) and cobalt(Co) and further including anions other than hydroxyl groups(OH); and a shell composed of transition metal hydroxides including cobalt(Co) and further including anions other than hydroxyl groups(OH), and a positive electrode active material for lithium secondary battery produced using the same.
