description The present invention relates to a negative electrode stack for a lithium secondary battery including: a negative electrode including lithium; and a negative electrode protective film formed on one surface of the negative electrode, wherein the negative electrode stack has an intaglio pattern formed on the surface of the negative electrode protective film. The negative electrode stack of the present invention, a lithium secondary battery including the same and a manufacturing method thereof form an intaglio pattern on one side of the negative electrode protective film, thereby inhibiting the growth of dendrites and increasing reaction sites by increasing the surface area of the electrode. 본 발명은 리튬을 포함하는 음극; 상기 음극의 일면 상에 형성된 음극 보호막;을 포함하는 음극 적층체이고, 상기 음극 적층체는 상기 음극 보호막 표면에 음각으로 형성된 음각 패턴을 갖는 것인, 리튬이차전지용 음극 적층체에 관한 것으로, 본 발명의 음극 적층체, 그를 포함하는 리튬이차전지 및 그의 제조방법은 음극 보호막의 일면에 음각 패턴을 형성함으로써, 덴드라이트의 성장을 억제하고, 전극의 표면적을 넓혀 반응 사이트(site)를 증가시킬 수 있다.
