  "textContent": "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 continuous concentration gradient from a core part to a surface part thereof, and is doped with transitional metal, such that the charge/discharge capacities and the power are significantly increased, and thereby it is possible to exhibit excellent performance under low temperature environments.",
