Abstract: The present invention relates to a polymer-sulfur copolymer, a preparation method thereof, and a lithium-sulfur battery including the same.In the case of the polymer-sulfur copolymer according to the present invention, since the carrier is polymerized, there is no possibility that the carrier is eluted, and since the sulfur is covalently bonded to the polymer and uniformly distributed in a certain size in the copolymer, when used as a positive electrode active material for the lithium-sulfur battery, the problem of elution of the polysulfide can be improved. In addition, the polymer-sulfur copolymer according to the present invention has a high sulfur impregnation amount, thereby making it possible to realize a high capacity battery.

Abstract: 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.
