The present invention relates to a lithium electrode, and a lithium secondary battery comprising the same and, more particularly, to a lithium electrode comprising: an electrode assembly comprising a porous metallic current collector and a lithium metal inserted into a pore formed on the metallic current collector; and a lithium ion conductive protection film formed by being coated on at least one side of the electrode assembly, and to a lithium secondary battery comprising the lithium electrode. According to the present invention, it is possible to enhance the performance of the lithium secondary battery by improving the contact surface area between the lithium metal and the current collector, and it is possible to enhance the stability of the lithium secondary battery by preventing lithium dendrite growth during the operation of the lithium secondary battery through uniformization of electron distribution within the lithium electrode. In addition, it is possible to prevent the phenomenon of exfoliation, during the charging or discharging of the battery, of the lithium ion conductive protection film for preventing the formation of lithium dendrite, even if the protection film is coated on the surface of the electrode. |
