Abstract
A negative electrode for a lithium secondary battery including a lithium metal layer and a protective layer including a three-dimensional structural body made of metal and lithium nitride on the lithium metal layer. The protective layer induces uniform ionic conductivity and electrical conductivity on the surface of the negative electrode. A method for manufacturing method a negative electrode for a lithium secondary battery including the steps of forming a metal hydroxide having a three-dimensional structure, forming a metal nitride having a three-dimensional structure by a nitridation reaction of the metal hydroxide of the three-dimensional structure; and transferring the metal nitride having the three-dimensional structure onto a lithium metal layer to form a protective layer. A lithium secondary battery including the negative electrode for a lithium secondary battery.
