Zusammenfassung:Disclosed is a high-output lithium secondary battery including: a cathode including a cathode active material having an average particle diameter (with respect to capacity) of 0.03 to 0.1 µm/mAh and a layered structure; an anode including crystalline graphite and amorphous carbon as anode active materials, wherein the amount of the amorphous carbon is between 40 and 100 wt% based on the total weight of the anode active materials; and a separator.
