Abstract: A lithium electrode and a lithium secondary battery including the same. More particularly, in the preparation of the lithium electrode, a protective layer for protecting the lithium metal is formed on the substrate, lithium metal may be deposited on the protective layer and then transferred to at least one side of the current collector to form a lithium electrode having a thin and uniform thickness, and the energy density of the lithium secondary battery using the lithium electrode thus manufactured may be improved.

Abstract: A lithium secondary battery prepared to a negative electrode free battery, and forming lithium metal on a negative electrode current collector through charge. The lithium secondary battery forms lithium metal while being blocked from the atmosphere, and since production of a surface oxide layer (native layer) formed on an existing negative electrode is fundamentally blocked, resulting battery efficiency and lifetime property decline may be prevented.

Abstract: A negative electrode for a lithium secondary battery, a method for preparing the same, and a lithium secondary battery including the same. The negative electrode for a lithium secondary battery is prepared while being blocked from atmosphere through a release coating film, which is effective in reducing a thickness of a surface oxide layer by delaying the surface oxide layer formation of lithium metal caused by oxygen and moisture in the atmosphere.
