The present invention relates to a negative electrode comprising a lithium metal layer, a lithium nitride thin film layer formed on at least one surface of the lithium metal layer, and a carbon thin film layer formed on the lithium nitride thin film layer, a method for producing the same, and a lithium secondary battery comprising the same. According to the present invention, the lithium nitride thin film layer and the carbon thin film layer formed on the lithium metal layer not only increase the specific surface area of the negative electrode but also prevent the side reaction due to direct contact between the lithium metal layer and the electrolyte, uniformly realize the current density distribution, By suppressing dendrite formation, the cyclic performance is improved and the overvoltage is reduced to improve the electrochemical performance of the lithium secondary battery. |
