摘要
Disclosed is a high energy density lithium secondary battery including: a cathode that includes, as cathode active materials, a first cathode active material represented by Formula 1 below and having a layered structure and a second cathode active material represented by Formula 2 below and having a spinel structure, wherein the amount of the first cathode active material is between 40 and 100 wt% based on the total weight of the cathode active materials; an anode including crystalline graphite and amorphous carbon as anode active materials, wherein the amount of the crystalline graphite is between 40 and 100 wt% based on the total weight of the anode active materials; and a separator.
