Disclosed are a positive active material for a lithium secondary battery, a method of preparing the same, and a lithium secondary battery including the same. In particular, the positive active material has a carbon sheet having a structure including 1 to 200 polycyclic nano sheets comprising a plurality of hexagonal rings each having six carbon atoms condensed and substantially aligned in a plane containing the hexagonal rings, the polycyclic nano sheets layered in a vertical direction to the plane containing the hexagonal rings; and an olivine-based compound particle disposed on the surface of the carbon sheet. |
