METHOD FOR SURFACE PATTERNING OF LITHIUM METAL, AND LITHIUM SECONDARY BATTERY ELECTRODE USING SAME

Document Type and Number:

WIPO Patent Application WO/2019/035692

Kind Code:

A2

Abstract:

The present invention relates to a method for surface patterning of lithium metal and a lithium secondary battery electrode using the same, the method comprising the steps of: forming an intaglio or embossed pattern having a predetermined size on a patterning substrate (S1); physically pressing lithium metal against the surface of the patterning substrate on which the pattern is formed, or applying liquid lithium onto the surface of the patterning substrate and then solidifying the same to form a predetermined pattern on the surface of the lithium metal (S2); and separating the lithium metal having the predetermined pattern formed thereon from the patterning substrate(S3).
