| abstract |
A nickel-based active material precursor for a lithium secondary battery, a method for producing the same, a nickel-based active material for a lithium secondary battery formed therefrom, and a lithium secondary battery including a positive electrode including the same. A shell comprising a secondary particle comprising a plurality of particulate structures, the particulate structure comprising a porous core portion and primary particles radially arranged on the porous core portion. And a nickel-based active material precursor for a lithium secondary battery in which the major axis of the primary particles is at least 50% of the primary particles constituting the surface of the secondary particles, and the major axis of the primary particles is the normal direction of the surface of the secondary particles. . If a nickel-based active material precursor for a lithium secondary battery is used, lithium can be easily inserted and removed, and a nickel-based active material having a short lithium ion diffusion distance can be obtained. In a lithium secondary battery manufactured using the method described above, the utilization rate of lithium is improved, the cracking of the active material due to charge and discharge is suppressed, and the capacity and life are increased.
