Title (EN) LITHIUM SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE AU LITHIUM
(KO) 리튬 이차전지
Abstract:
(EN) The present invention relates to a lithium secondary battery produced as an anode-free battery and having a lithium metal formed on an anode current collector in the form of a three-dimensional structure by means of charging. The lithium secondary battery forms the lithium metal in a state of being blocked off from air, such that a native oxide layer, which is conventionally formed on an anode, is not generated at all, and the lithium metal is formed on the anode current collector in the form of a three-dimensional structure, thereby having an excellent lithium dendrite growth inhibiting effect. Therefore, it is possible to prevent reduction of battery efficiency and service life characteristics.
(FR) La présente invention concerne une batterie secondaire au lithium qui est produite en tant que batterie sans anode et qui a un métal lithium formé sur un collecteur de courant d'anode sous la forme d'une structure tridimensionnelle au moyen d'une charge. La batterie secondaire au lithium forme le métal lithium dans un état d'étanchéité à l'air, de telle sorte qu'une couche d'oxyde natif, qui est classiquement formée sur une anode, ne soit absolument pas générée, et le métal lithium est formé sur le collecteur de courant d'anode sous la forme d'une structure tridimensionnelle, ce qui permet d'obtenir un excellent effet d'inhibition de la croissance de dendrites de lithium. Par conséquent, il est possible d'empêcher la réduction de l'efficacité de la batterie et des caractéristiques de durée de vie.
(KO) 본 발명은 음극 프리 전지로 제조되어 충전에 의해 3차원 구조체 형태의 음극 집전체 상에 리튬 금속을 형성한 리튬 이차전지에 관한 것이다. 상기 리튬 이차전지는 대기와 차단된 상태에서 리튬 금속을 형성하여 종래 음극 상에 형성되는 표면 산화막(native oxide layer)의 생성이 원천적으로 일어나지 않고, 3차원 구조체 형태의 음극 집전체 상에 리튬 금속이 형성되어 리튬 덴드라이트 성장 억제 효과가 우수하므로 이에 따른 전지의 효율 및 수명 특성 저하를 방지할 수 있다.
