Abstract
The present invention is related to a lithium anode, a method of the manufacturing the same and a battery using the anode. The lithium anode comprises a metal layer (or alloy layer) that is inert to lithium and a metal layer (or alloy layer) that is reactive with lithium. The two layers may form a temporary protective layer on the lithium surface, thus providing a smooth surface. By obtaining the smooth surface, an upper polymer layer and an inorganic layer may be deposited without any difficulty and the adhesive force may be strong. Thus, the lithium anode according to the present invention has superior cycling characteristics and improved storage characteristics.
