Summary:The present invention relates to a current collector, a lithium electrode comprising the same, and a lithium secondary battery. More specifically, in a three-dimensional structure current collector with pores formed therein, seed metal is deposited on an upper surface facing a separator and a lower surface on the opposite side to allow the lower surface to have a lower reduction potential than that of the lower surface, thereby moving lithium ions to the lower surface of the three-dimensional structure current collector to prevent the growth of lithium dendrites. 본 발명은 집전체, 이를 포함하는 리튬 전극 및 리튬 이차전지에 관한 것이다. 보다 상세하게는, 기공이 형성된 3차원 구조 집전체에서 분리막과 마주보는 상면과 반대편인 하면에 시드 금속을 증착시켜 상기 하면이 하면에 비해 낮은 환원 전위를 갖게 함으로써, 리튬 이온이 상기 3차원 구조 집전체의 하면으로 이동하게 하여 리튬 덴드라이트의 성장을 방지할 수 있다.
