Abstract
There are provided a method of preparing an irreversible additive in which a content of a Li-based by-product such as unreacted lithium oxide generated in a process of preparing lithium nickel-based oxide is decreased, which may significantly reduce gelation of a composition including the irreversible additive, a cathode material including the irreversible additive prepared by the same, and a lithium secondary battery including the cathode material.
