Beschreibung
Zusammenfassung:	The present invention relates to a method for manufacturing a negative electrode for a lithium secondary battery including a protective layer integrated with a lithium metal, and a manufacturing device used therefor. The present invention includes the steps of: introducing a lithium metal into a reaction unit; and forming a protective layer by injecting nitrogen gas into the reaction unit and reacting the nitrogen gas with the lithium metal. According to the present invention, during the manufacture of a negative electrode for a lithium secondary battery, since the lithium metal is not exposed to the air and is introduced into the reaction unit, deterioration of the lithium metal can be suppressed. 본 발명은 리튬 금속과 일체화된 보호층을 포함하는 리튬이차전지용 음극의 제조방법 및 이에 사용되는 제조장치에 관한 것이다.
