LITHIUM ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING THE SAME |
摘要 |
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. |
