Abstract
A method for preparing a lithium electrode, and in particular, a lithium electrode having a thin and uniform thickness may be prepared by forming a protective layer capable of protecting lithium metal on a substrate first, depositing lithium metal on the protective layer, and then transferring the deposited lithium metal layer on a current collector, for instance a Cu current collector, when preparing a lithium electrode, and a lithium secondary battery using the lithium electrode prepared as above may have enhanced energy density.
