Abstract

The present invention relates to a positive electrode active material which is formed such that a lithium ion diffusion path in a lithium composite oxide constituting a positive electrode active material is directed to a specific crystal plane, and has improved electrochemical properties and stability by improving the growth of the crystal plane to which the lithium ion diffusion path is directed, and a lithium secondary battery using the same.
