Abstract:
(EN) The present invention relates to a copper foil current collector having high adhesion to an anode active material of a Li secondary battery. The present invention provides an electrolytic copper foil having a first surface and a second surface, the electrolytic copper foil comprising: a first protective layer on a first surface side; a second protective layer on a second surface side; and a copper film between the first and second protective layers, wherein the electrolytic copper foil has an oxygen thickness (OT) of 1.5 nm or more on the second surface. According to the present invention, it is possible to provide an electrolytic copper foil current collector for a Li secondary battery having high adhesion to an active material and low electric resistance.
(FR) La présente invention concerne un collecteur de courant à base de feuille de cuivre ayant une adhérence élevée à un matériau actif d'anode d'une pile rechargeable au lithium. La présente invention concerne une feuille de cuivre électrolytique ayant une première surface et une seconde surface, la feuille de cuivre électrolytique comprenant : une première couche de protection sur un côté de première surface ; une seconde couche de protection sur un côté de seconde surface ; un film de cuivre entre les première et seconde couches de protection, la feuille de cuivre électrolytique ayant une épaisseur d'oxygène (OT) de 1,5 nm ou plus sur la seconde surface. Selon la présente invention, il est possible de fournir un collecteur de courant à base de feuille de cuivre électrolytique pour une pile rechargeable au lithium ayant une adhérence élevée à un matériau actif et une faible résistance électrique.
(KO) 본 발명은 Li 이차전지의 음극 활물질과 높은 밀착력을 갖는 동박 집전체에 관한 것이다. 본 발명은 제1 표면 및 상기 제2 표면을 갖는 전해동박에 있어서, 상기 제1 표면 측의 제1 보호층; 상기 제2 표면 측의 제2 보호층; 및 상기 제1 및 제2 보호층 사이의 구리막을 포함하고, 상기 전해동박은 상기 제2 표면에서의 산소함유부의 두께(Oxygen Thickness; OT)가 1.5nm 이상인 것을 특징으로 하는 전해동박을 제공한다. 본 발명에 따르면, 활물질과 높은 밀착력을 가지면서 낮은 전기 저항을 갖는 Li 이차전지용 전해동박 집전체를 제공할 수 있게 된다.
