The present disclosure relates to a negative electrode for a secondary battery and a manufacturing method thereof, the negative electrode including a negative electrode current collector and a lithium metal. The present disclosure provides a negative electrode for a secondary battery including a negative electrode current collector; a lithium metal layer having a fine pattern formed on the negative electrode collector; and a protective layer formed along the surface of the lithium metal layer having the fine pattern, and a method for forming a lithium metal layer having a fine pattern formed thereon and the protective layer.In the negative electrode for a secondary battery according to the present disclosure, effective current density may be reduced and battery capacity may be maximized by forming a fine pattern on a surface of a lithium metal included in a negative electrode to increase an electrode specific surface area. Also, an increase in battery resistance may be prevented and charge and discharge cycle efficiency may be improved by forming a pattern on a surface of a lithium metal to improve an interfacial adhesion between a lithium metal and a protective layer thereof.
