An electrode and a lithium secondary battery including the same. By preparing an electrode including an electrode active layer formed using a structure capable of supporting an electrode active material, safety and charge and discharge properties of a battery are improved due to morphological characteristics of the electrode active material being supported inside the structure.

Electrode and lithium secondary battery comprising same

A structure, and more specifically a tube-shaped structure having an inner surface and two ends, wherein one or both ends are open and the inner surface is exposed through said one or both open ends, and a metal provide on the inner surface. Also, an electrode active material, such as lithium metal, on the metal included on the inner surface of the tube.

Tube structure having metal on inner surface thereof

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.

Lithium secondary battery

An electroplating solution for lithium metal, and a method for preparing a lithium metal electrode using the same, and in particular, while preparing a lithium metal electrode using electroplating, a lithium metal electrode having enhanced surface properties may be prepared by electroplating using a plating solution including a lithium nitrogen oxide and a metal nitrogen oxide, and, by using such a lithium metal electrode in a battery, lifetime properties of the battery may be enhanced.
