Beschreibung
Zusammenfassung:	The present invention relates to a lithium secondary battery including a positive electrode including a lithium manganese-based first positive electrode active material having a spinel structure doped and coated and a lithium nickel-manganese-cobalt-based second positive active material, a negative electrode including artificial graphite having a specific surface area (BET) of 0.1-1.2 m2/g and at least one selected from the group consisting of soft carbon and natural graphite which have a greater specific surface area than the artificial graphite, a separator interposed between the positive electrode and the negative electrode, and an electrolyte.
