Abstract
The present invention relates to a Li-rich antiperovskite-coated LCO-based lithium complex, a method of preparing the same, and a positive electrode active material and a lithium secondary battery, both of which include the LCO-based lithium complex. When a lithium complex in which a coating layer of a compound having a lithium-rich antiperovskite (LiRAP) crystal structure is formed on surfaces of LCO-based particles is applied as the positive electrode active material, the lithium complex is favorable for batteries which are operated at a high voltage, has high lithium ion conductivity, and can be applied to lithium secondary batteries which are driven at a high temperature due to high thermal stability.
