Abstract:
The present invention provides a positive electrode active material for a lithium secondary battery having a core-shell structure which comprises: a core composed of lithium transition metal oxides including nickel(Ni), manganese(Mn) and cobalt(Co); and a shell composed of lithium transition metal oxides including cobalt(Co), wherein an inorganic material layer is further formed by coating on the surface of the shell.
