Title (EN) NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, METHOD FOR MANUFACTURING SAME, AND LITHIUM SECONDARY BATTERY COMPRISING SAME
(FR) ÉLECTRODE NÉGATIVE POUR ACCUMULATEUR AU LITHIUM, SON PROCÉDÉ DE FABRICATION, ET ACCUMULATEUR AU LITHIUM LA COMPRENANT

Abstract:
(EN) The present invention relates to a negative electrode for a lithium secondary battery, a method for producing the same, and a lithium secondary battery comprising the same. Since the negative electrode for a lithium secondary battery according to the present invention is manufactured in a state of being cut off from the atmosphere through a release coating film, there is an effect that the thickness of the surface oxide film is reduced by delaying the formation of the surface oxide film of lithium metal due to oxygen and moisture in the atmosphere.
(FR) La présente invention porte sur une électrode négative pour un accumulateur au lithium, son procédé de production, et un accumulateur au lithium la comprenant. Puisque l’électrode négative pour un accumulateur au lithium selon la présente invention est fabriquée dans un état où elle est coupée de l’atmosphère par une pellicule de revêtement de décollage, il y a un effet tel que l’épaisseur de la pellicule d’oxyde de surface est réduite en retardant la formation de la pellicule d’oxyde de surface du lithium métallique causée par l’oxygène et l’humidité de l’atmosphère.
(KO) 본 발명은 리튬 이차전지용 음극, 이의 제조방법 및 이를 포함하는 리튬 이차전지에 관한 것이다. 본 발명에 따른 리튬 이차전지용 음극은 이형 코팅필름을 통해 대기와 차단된 상태로 제조되므로, 리튬 금속의 대기 중 산소 및 수분으로 인한 표면 산화막의 형성을 지연시켜, 표면 산화막의 두께를 감소시키는 효과가 있다.
