HIGH OUTPUT LITHIUM SECONDARY BATTERY HAVING ENHANCED OUTPUT DENSITY CHARACTERISTIC

摘要

Disclosed is a high-output 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 second cathode active material is between 40 and 100 wt% based on the total weight of the cathode active materials; an anode including crystalline graphite having a specific surface area (with respect to capacity) of 0.005 to 0.013 m 2 /mAh as an anode active material; and a separator.
