摘要： Disclosed are a cathode material for a lithium secondary battery and a method of manufacturing the same. For instance, the lithium secondary battery may have a high energy density by using only a single cathode material. Particularly, the cathode material for a lithium secondary battery includes a Li—[Mn—Ti]—Al—O-based cathode active material; and a carbon nanotube (CNT) attached to the surface of the cathode active material in an acid-treated state to be formed as a composite.
