Abstract
A lithium electrode and a lithium secondary battery including the same, which includes a first protective layer and a second protective layer sequentially formed on at least one surface of lithium metal layer. The second protective layer contains a cross-linked ion conductive electrolyte in the interior and on the surface of the electrically conductive matrix, and thus the first protective layer has higher ion conductivity than the second protective layer, thereby preventing electrons from being concentrated into lithium dendrites formed from the lithium metal to inhibit the growth of lithium dendrites, and at the same time, physically inhibiting the growth of lithium dendrites by the second protective layer.
