摘要： A negative electrode including a lithium metal layer, a lithium nitride thin film layer formed on at least one surface of the lithium metal layer, and a carbon-based thin film layer formed on the lithium nitride thin film layer, a method for preparing the same, and a lithium secondary battery including the same. A lithium nitride thin film layer and a carbon-based thin film layer formed on a lithium metal layer obtains current density distribution uniformly by blocking side reactions caused by a direct contact between the lithium metal layer and an electrolyte as well as increasing a specific surface area of a negative electrode, and enhances cycle performance and reduces an overvoltage by suppressing lithium dendrite formation to improve electrochemical performance of a lithium secondary battery.

摘要： 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.
