Nickel-based active material precursor for lithium secondary battery, preparing method thereof, nickel-based active material for lithium secondary battery formed thereof, and lithium secondary battery comprising positive electrode including the nickel-based active material

摘要

It includes a porous core and a porous shell, the porosity of the porous shell is larger than that of the porous core, and a dense intermediate layer is disposed between the porous core and the porous shell, The porosity of the dense intermediate layer is smaller than the porosity of the porous core and the porosity of the porous shell, including a nickel-based active material precursor for a lithium secondary battery, a method of manufacturing the same, a nickel-based active material for lithium secondary batteries formed therefrom, and a positive electrode comprising the same. A lithium secondary battery is presented.
