Abstract
A lithium electrode and a lithium secondary battery including the same. By using an olefin-based ion conducting polymer as a protective layer-forming material of a lithium electrode having a protective layer formed on a lithium metal layer, the lithium electrode may be protected from moisture or open air during a lithium electrode preparation process, lithium dendrite formation and growth from the lithium electrode may be prevented, and performance of a battery using the lithium electrode may be enhanced.
