Abstract
Disclosed is a lithium secondary battery including: an electrode assembly including a cathode including a cathode mixture layer formed on a cathode current collector, an anode including an anode mixture layer formed on an anode current collector, and a separator disposed between the cathode and the anode; and an electrolyte, wherein the anode includes lithium titanium oxide (LTO) as an anode active material, and four planes of the cathode mixture layer have the same or greater length than four planes of the anode mixture layer and thus the cathode mixture layer has the same or greater area than the anode mixture layer.
