Abstract
A method of preparing a lithium metal oxide having a nickel oxide layer formed on a surface thereof includes (1) complexing a nickel precursor onto a surface of a lithium metal oxide; and (2) calcining, through a heat treatment, the lithium metal oxide—the surface of which is complexed with the nickel precursor—obtained in step (1).
