Lithium electrode and lithium secondary battery comprising the same
The present disclosure relates to a lithium electrode, comprising an electrode composite comprising a porous metallic current collector, and lithium metal inserted into pores present in the metallic current collector; and a protective membrane for lithium ion conduction, the protective membrane being formed on at least one surface of the electrode composite.The lithium electrode according to the present disclosure can increase contact surface between lithium metal and a current collector to improve the performances of a lithium secondary battery, and can exhibit uniform electron distribution therein to prevent the growth of lithium dendrites during the operation of a lithium secondary battery, thereby improving the safety of a lithium secondary battery. Furthermore, even though the lithium electrode is coated with a protective membrane for lithium ion conduction on the surface thereof, the protective membrane can be prevented from being peeled off during the charge and discharge of a lithium secondary battery.
