A lithium metal is physically pressed to a silicon wafer having a uniform intaglio or embossed pattern formed thereon in advance, or liquid lithium is applied to the silicon wafer and may then be cooled in order to form a uniform pattern on the surface of the lithium metal.

Lithium metal patterning and electrochemical device using the same

A method for patterning a lithium metal surface, including the steps of (S1) forming an intaglio or relief pattern having a predetermined size on a patterning substrate; (S2) either (a) compressing lithium metal physically to a surface of the patterning substrate having the pattern formed thereon to form the predetermined pattern on the surface of the lithium metal, or (b) applying liquid lithium to the surface of the patterning substrate having the pattern formed thereon and solidifying the liquid lithium to form the predetermined pattern on the surface of the lithium metal; and (S3) separating the lithium metal having the predetermined pattern formed thereon from the patterning substrate, wherein the patterning substrate is at least one selected from a silicon wafer or polycarbonate substrate.
