Abstract:
(EN) The present invention relates to a method for manufacturing an anode for a secondary battery, and the anode, the method comprising: a first step of preparing a lithium metal sheet, which has thin film-shaped lithium metal coated on or attached to a release film and is wound into a roll; a second step of manufacturing an anode having the lithium metal stacked thereon, by stacking the lithium metal sheet such that the lithium metal is adjacent to an anode mixture; and a third step of manufacturing an anode by applying pressure to the anode having the lithium metal stacked thereon, wherein the release film is coated with silicon. The method for manufacturing an anode, of the present invention, has an effect of uniformly stacking or joining lithium metal, which is difficult to handle, onto the anode mixture of a secondary battery, and has an advantage of improving a pre-lithiation rate by using lithium metal having a pattern.
(FR) La présente invention concerne un procédé de fabrication d'une anode de batterie secondaire, et l'anode, le procédé comprenant : une première étape consistant à préparer une feuille de lithium métal, comportant un lithium métal sous forme de film mince revêtant ou étant fixé à un film de libération, et étant enroulée en un rouleau ; une deuxième étape consistant à fabriquer une anode sur laquelle est empilé le lithium métal, par un empilement de la feuille de lithium métal de sorte que le lithium métal soit adjacent à un mélange d'anode ; et une troisième étape consistant à fabriquer une anode par une application d'une pression à l'anode sur laquelle est empilé le lithium métal, le film de libération étant revêtu de silicium. Le procédé de fabrication d'une anode, selon la présente invention, a pour effet d'empiler ou d'assembler uniformément un lithium métal, qui est difficile à manipuler, sur le mélange d'anode d'une batterie secondaire, et offre l'avantage d'améliorer un taux de pré-lithiation au moyen d'un lithium métal ayant un motif.
(KO) 본 발명은 이차전지용 음극의 제조방법 및 음극에 관한 것으로, 이형 필름 상에 박막 형태의 리튬 금속이 코팅 또는 부착되어 롤로 권취된 리튬 금속 시트를 준비하는 제 1 단계; 음극 합제 상에 리튬 금속이 인접하도록 상기 리튬 금속 시트를 적층하여 리튬 금속이 적층된 음극을 제조하는 제 2 단계; 및 리튬 금속이 적층된 음극에 압력을 인가하여 음극을 제조하는 제 3 단계; 로 이루어지고, 상기 이형 필름은 실리콘이 코팅된 것을 특징으로 하는 이차전지용 음극의 제조방법이다. 본 발명의 음극의 제조방법은 취급이 까다로운 리튬 금속을 이차전지 음극 합제 상에 균일하게 적층 또는 접합시키는 효과가 있으며, 패턴이 있는 리튬 금속을 이용함으로써, 전리튬화의 속도를 향상시키는 이점이 있다.
