Summary:The present invention provides a prelithiation apparatus for preventing an electrode from being damaged, during a prelithiation process, by by-products generated by contact between a lithium source, such as a lithium metal sheet or a lithium metal powder, and an electrolyte solution used in a lithium process. The prelithiation apparatus has two reaction tanks consisting of a first reaction tank and a second reaction tank, wherein an electrolyte solution of the first reaction tank and an electrolyte solution of the second reaction tank are connected by a salt bridge, at least a portion of a negative electrode to be lithiated is immersed in the electrolyte solution of the first reaction tank, and at least a portion of a lithium source that is to supply lithium ions is immersed in the electrolyte solution of the second reaction tank. La présente invention concerne un appareil de prélithiation pour empêcher une électrode d'être endommagée, au cours d'un processus de prélithiation, par des sous-produits générés par contact entre une source de lithium, telle qu'une feuille métallique de lithium ou une poudre métallique de lithium, et une solution électrolytique utilisée dans un procédé de lithium. L'appareil de prélithiation comprend deux réservoirs de réaction constitués d'un premier réservoir de réaction et d'un second réservoir de réaction, une solution électrolytique du premier réservoir de réaction et une solution électrolytique du second réservoir de réaction étant reliées par un pont salin, au moins une partie d'une électrode négative devant être lithiée est immergée dans la solution électrolytique du premier réservoir de réaction, et au moins une partie d'une source de lithium qui est destinée à fournir des ions lithium est immergée dans la solution électrolytique du second réservoir de réaction. 본 발명은, 전리튬화 공정시에 리튬 금속 시트 또는 리튬 금속 분말과 같은 리튬 소스와 리튬 공정에 사용되는 전해액의 접촉에 의해 발생되는 부산물이 전극을 손상시키는 것을 방지하기 위한 전리튬화 장치로서, 제1 반응조 및 제2 반응조로 구성된 2개의 반응조를 구비하되, 상기 제1 반응조의 전해액과 제2 반응조의 전해액은 염다리(salt bridge)에 의해 연결되어 있고, 상기 제1 반응조의 전해액에는 리튬화시킬 음극의 적어도 일부가 침지되어 있고, 상기 제2 반응조의 전해액에는 리튬 이온을 공급할 리튬 소스의 적어도 일부가 침지되어 있는 전리튬화 장치가 제공된다.
