Abstract
A lithium electrode and a lithium secondary battery including the same. The lithium electrode has a surface oxide layer with a controlled thickness and surface roughness. The lithium electrode may be used as a negative electrode of a lithium secondary battery, for example, a lithium-sulfur secondary battery. A lithium-sulfur battery including the lithium electrode has an enhanced lifetime due to suppression of side reactions with polysulfide.
