Title (EN) LITHIUM ELECTRODE AND LITHIUM SECONDARY BATTERY COMPRISING SAME
(FR) ÉLECTRODE AU LITHIUM ET BATTERIE SECONDAIRE AU LITHIUM COMPRENANT CELLE-CI
(KO) 리튬 전극 및 그를 포함하는 리튬 이차전지
Abstract: front page image
(EN)The present invention relates to a lithium electrode, and a lithium secondary battery comprising the same and, more particularly, to a lithium electrode comprising: a porous metallic current collector; and a lithium metal inserted into a pore formed on the metallic current collector, and to a lithium secondary battery comprising the lithium electrode. According to the present invention, it is possible to enhance the performance of the lithium secondary battery by improving the contact surface area between the lithium metal and the current collector, and it is possible to enhance the stability of the lithium secondary battery by preventing lithium dendrite growth during the operation of the lithium secondary battery through uniformization of electron distribution within the lithium electrode.
(FR)L'invention concerne une électrode au lithium et une batterie secondaire au lithium comprenant celle-ci. Elle concerne plus particulièrement une électrode au lithium comprenant: un collecteur de courant métallique poreux; et un métal lithium inséré dans un pore formé sur le collecteur de courant métallique; et une batterie secondaire au lithium comprenant l'électrode de lithium. Selon l'invention, les performances de la batterie secondaire au lithium peuvent être améliorées par amélioration de la zone de surface de contact entre le métal lithium et le collecteur de courant. La stabilité de la batterie secondaire au lithium peut également être renforcée si l'on empêche la croissance de dendrites de lithium pendant le fonctionnement de la batterie secondaire au lithium, par une répartition uniforme des électrons à l'intérieur de l'électrode au lithium.
(KO)본 발명은 리튬 전극 및 그를 포함하는 리튬 이차전지에 관한 것으로서, 더욱 자세하게는 다공성 금속 집전체; 및 상기 금속 집전체에 형성된 기공에 삽입된 리튬 금속;을 포함하는 리튬 전극 및 그를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따르면, 리튬 금속과 집전체와의 접촉 표면적이 향상됨으로써 리튬 이차전지의 성능을 향상시킬 수 있고, 리튬 전극내의 전자분포의 균일화를 통해 리튬 이차전지의 구동 시에 리튬 덴드라이트 성장을 방지하여, 리튬 이차전지의 안전성을 향상시킬 수 있다.
