Abstract
A method for pretreating a lithium electrode, and a lithium metal battery, and in particular, a method for stabilizing a lithium electrode through pretreatment of being immersed in a composition for forming a solid electrolyte interphase, and a lithium metal battery including such a lithium electrode. Effects of decreasing interfacial resistance and enhancing Li charge and discharge efficiency are obtained when forming a solid electrolyte interphase (SEI) on a lithium electrode in advance using a pretreatment process of the lithium electrode, and then using the SEI layer-formed lithium electrode in a lithium metal battery.
