    Abstract: A method for manufacturing a lithium electrode, more particularly, a method for manufacturing a lithium electrode having a thin and uniform thickness by, when manufacturing the lithium electrode, first forming a protective layer capable of protecting lithium metal on the surface treated substrate with a plasma and corona process, and depositing lithium metal on the protective layer and then transferring the deposited lithium metal layer to a current collector. The energy density of the lithium secondary battery manufactured using the lithium electrode thus manufactured can be improved.
