Abstract

A lithium battery cathode active material and a preparation method therefor are described. The material has an orientation formed by firing a density gradient precursor in which the density gradually changes from the inside of second particles, formed as an aggregate of primary particles, to the outside of the particles. The lithium battery cathode active material has an oriented structure, and thus can have a long lifespan and high-capacity characteristics.
