Zusammenfassung: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). La présente invention concerne un procédé de formation de motifs en surface de métal lithium et une électrode de batterie secondaire au lithium l'utilisant, le procédé comprenant les étapes consistant à : former un motif en creux ou en relief ayant une taille prédéfinie sur un substrat de formation de motifs (S1); presser physiquement le métal lithium contre la surface du substrat de formation de motif sur lequel le motif est formé, ou appliquer du lithium liquide sur la surface du substrat de formation de motif et solidifier ensuite celui-ci pour former un motif prédéfini sur la surface du métal lithium (S2); et séparer le métal lithium sur lequel est formé le motif prédéfini du substrat de formation de motifs (S3). 본 발명은 (S1) 소정 크기의 음각 또는 양각 패턴을, 패터닝 기판에 형성하는 단계; (S2) 상기 패턴이 형성되어 있는 상기 패턴닝 기판의 표면에 리튬 금속을 물리적으로 압착하거나, 또는 액상의 리튬을 도포한 이후 고화시킴으로써 리튬 금속의 표면에 일정한 패턴을 형성하는 단계; 및 (S3) 상기 일정한 패턴이 형성된 리튬 금속을 상기 패터닝 기판으로부터 분리하는 단계를 포함하는 리튬 금속 표면의 패터닝 방법 및 이를 이용한 리튬 이차전지용 전극에 관한 것이다.
