Abstract
The present invention relates to a lithium composite oxide including a coating layer having a boron-containing oxide and a lithium secondary battery including the same. More particularly, the present invention relates to a lithium composite oxide improved in lifetime and capacity characteristics by inducing a predetermined correlation between the molar ratio of nickel in a lithium composite oxide including a coating layer having a boron-containing oxide and a full width at half-maximum (FWHM; deg., 2θ) of a (104) peak among XRD peaks defined by the hexagonal lattice with an R-3m space group, and a lithium secondary battery including the same.
