Multi-layer structured lithium metal electrode and method for manufacturing same
The present invention relates to a multi-layer structured lithium metal electrode and a method for manufacturing the same and, specifically, to a multi-layer structured lithium metal electrode comprising: a buffer layer of lithium nitride (Li3N) formed on a lithium metal plate; and a protective layer of LiBON formed on the buffer layer, and to a method for manufacturing a multi-layer structured lithium metal electrode by continuously forming a lithium nitride buffer layer and a LiBON protective layer on a lithium metal plate through continuous reactive sputtering multi-layer structured lithium metal electrode multi-layer structured lithium metal electrode lithium metal plate multi-layer structured lithium metal electrode lithium metal plate. The multi-layer structured lithium metal electrode of the present invention can protect the reactivity of the lithium metal from moisture or an environment within a battery, and prevent the formation of dendrites, by forming the protective layer.
