Beschreibung
Zusammenfassung:	The present invention pertains to a negative electrode for a lithium secondary battery, a method for manufacturing same, and a lithium secondary battery including same. More specifically, the negativeelectrode for a lithium secondary battery according to the present invention has a protective layer containing a three-dimensional structure composed of metal and lithium nitride, and thus uniform ionic conductivity and electrical conductivity can be induced on the surface of the negative electrode. 本发明涉及锂二次电池用负极、其制造方法以及包含该负极的锂二次电池。更具体地，在本发明的锂二次电池用负极中，可以形成包括由金属和氮化锂制成的三维结构体的保护层，从而在负极的表面上诱导均匀的离子电导率和电子电导率。
