Abstract

A lithium metal oxide composite for a lithium secondary battery includes a core portion formed of a Mn metal compound and a shell portion formed of a three-component system metal compound at an outside of the core portion. A method of preparing a lithium metal oxide composite for a lithium secondary battery includes: mixing an Mn metal salt aqueous solution, a chelate agent, and a pH regulator to precipitate a first precursor; thermally treating the obtained first precursor; mixing the thermally treated first precursor with a three component system metal salt aqueous solution, a chelate agent, and a pH regulator to precipitate a second precursor; and mixing the obtained second precursor with a lithium-containing compound to synthesize a powder via a firing.
