摘要： An electrode for a lithium secondary battery, which may be applied to the lithium secondary battery to increase cycling performance and efficiency of the battery, and a manufacturing method thereof. When the electrode for the lithium secondary battery of the present invention is applied to the lithium secondary battery, uniform deposition and stripping of lithium metals occur throughout the surface of the electrode when charging/discharging the battery, thereby inhibiting uneven growth of lithium dendrites and improving cycle and efficiency characteristics of the battery. Further, the electrode for the lithium secondary battery of the present invention exhibits remarkably high flexibility, as compared with existing electrodes including a metal current collector and an active material layer, thereby improving processability during manufacture of the electrode and assembling the battery.
