Abstract: front page image
(EN) 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. 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. In addition, the formation of the buffer layer prevents the deterioration of ion conductivity, caused by an oxide layer formed on the lithium metal plate in the process of forming the protective layer.
(FR) La présente invention porte sur une électrode de lithium métallique à structure multicouche et son procédé de fabrication, et plus précisément sur une électrode de lithium métallique à structure multicouche comprenant : une couche tampon de nitrure de lithium (Li3N) formée sur une plaque de lithium métallique ; et une couche de protection en LiBON formée sur la couche tampon, et sur un procédé de fabrication d'une électrode de lithium métallique à structure multicouche par formation en continu d'une couche tampon de nitrure de lithium et d'une couche de protection en LiBON sur une plaque de lithium métallique par pulvérisation cathodique réactive en continu. L'électrode de lithium métallique à structure multicouche de la présente invention peut protéger la réactivité du lithium métallique contre l'humidité ou un environnement à l'intérieur d'une batterie, et empêcher la formation de dendrites, par formation de la couche de protection. En outre, la formation de la couche tampon empêche la détérioration de la conductivité ionique, provoquée par une couche d'oxyde formée sur la plaque de lithium métallique dans le processus de formation de la couche de protection.
(KO) 본 발명은 다층구조의 리튬금속 전극 및 이의 제조방법에 관한 것으로, 리튬 금속판 상에 질화리튬(Li3N)으로 이루어진 버퍼층을 형성하고, 상기 버퍼층 상에 LiBON으로 이루어진 보호층을 형성한 다층구조의 리튬금속 전극과 반응성 스퍼터링법으로 연속하여 리튬금속판에 질화리튬 버퍼층과 LiBON 보호층을 연속하여 형성하는 다층구조의 리튬금속 전극의 제조방법에 관한 것이다. 본 발명의 다층구조의 리튬금속 전극은 보호층의 형성으로 리튬금속의 수분이나 전지내 환경에서의 반응성을 보호하고 덴드라이트 형성을 방지할 수 있다. 또한, 버퍼층의 형성으로 보호층의 형성과정에서 리튬금속판 상에 산화물층이 형성되어 이온전도도가 저하될 수 있는 문제를 방지한다.
