==Original Abstract Submitted==

Herein are provided a positive electrode active material for a lithium secondary battery comprising a lithium transition metal oxide on which a crumpled graphene-derived coating layer is formed, and a method of preparing the same. The crumpled graphene has a thickness of 0.1 to 10 nm. In the positive electrode active material, the thin and uniform crumpled graphene-derived coating layer effectively imparts electrical conductivity to the lithium transition metal oxide. When the positive electrode active material is applied to a lithium secondary battery, the performance of the lithium secondary battery, particularly the discharge capacity at a high C-rate is improved.
