| Zusammenfassung: | Disclosed is a lithium secondary battery, including a cathode, an anode and a non-aqueous electrolyte, wherein the cathode includes a cathode active material containing lithium-metal oxide of which at least one of metals has a concentration gradient region between a core part and a surface part thereof, and the anode includes graphite having an average lattice distance d002 of 3.356 to 3.365 , thereby having excellent high-temperature storage and life-span properties. |
