Abstract
The present invention relates to an cathode active material for lithium secondary battery and a lithium secondary battery including the same, and more specifically, it relates to an anode active material for lithium secondary battery which includes a concentration gradient layer having a controlled thickness and a shell layer on the periphery of the core layer of the anode active material having a layered structure and in which the lithium ion diffusion paths in the primary particles and the secondary particles are formed to exhibit directivity in a specific direction, and a lithium secondary battery including the same.
