Abstract
A lithium electrode and a lithium secondary battery the same are disclosed. More specifically, a lithium electrode is disclosed that can increase the lifetime of the battery by providing a protective layer containing a copolymer containing an acetal functional group forming a stable SEI layer through a chemical reaction with lithium metal and a fluorine-based functional group capable of forming a LiF-rich SEI layer on the surface of the lithium metal to inhibit the formation of lithium dendrite and inhibit the side reaction of lithium metal and electrolyte solution.
