Abstract
Provided are a nickel-based active material precursor for a lithium secondary battery including a porous core and a shell on the porous core, the shell having a radial arrangement structure with a higher density than that of the porous core, wherein the nickel-based active material precursor have a size of 9 μm to 14 μm, and the porous core has a volume of about 5% by volume to about 20% by volume based on the total volume of the nickel-based active material precursor; a method of preparing the nickel-based active material precursor; a nickel-based active material produced from the nickel-based active material; and a lithium secondary battery including a cathode containing the nickel-based active material.
