Abstract:
(EN) The present invention relates to an electrolytic copper foil for a secondary battery, having excellent flexural resistance, and a method for producing the electrolytic copper foil and, more specifically, to an electrolytic copper foil for a secondary battery, which has excellent flexural resistance even without the use of many additives in a copper electrolyte when producing a copper foil, and to a method for producing the electrolytic copper foil. The electrolytic copper foil for a secondary battery according to the present invention is an electrolytic copper foil for a secondary battery, which is produced from a plating solution, containing total organic carbon (TOC), cobalt and arsenic, by using a drum and is coated with a cathode active material, wherein the ratio between the TOC, cobalt and arsenic contained in the electrolytic copper foil follows the following formula 1: [Formula 1] TOC / (cobalt + arsenic) = 1.30 - 1.55.
(FR) La présente invention concerne une feuille de cuivre électrolytique pour une batterie secondaire, ayant une excellente résistance à la flexion, et un procédé de production de la feuille de cuivre électrolytique et, plus spécifiquement, une feuille de cuivre électrolytique pour une batterie secondaire, qui présente une excellente résistance à la flexion même sans utiliser de nombreux additifs dans un électrolyte de cuivre lors de la production d'une feuille de cuivre, et un procédé de production de la feuille de cuivre électrolytique. La feuille de cuivre électrolytique pour une batterie secondaire selon la présente invention est une feuille de cuivre électrolytique pour une batterie secondaire, qui est produite à partir d'une solution de placage, contenant du carbone organique total (COT), du cobalt et de l'arsenic, à l'aide d'un tambour et est revêtu d'un matériau actif de cathode, le rapport entre le COT, le cobalt et l'arsenic contenus dans la feuille de cuivre électrolytique suit la formule 1 suivante : [formule 1] COT/ (cobalt + arsenic) = 1,30 - 1,55.
(KO) 본 발명은 내굴곡성이 우수한 이차전지용 전해동박 및 그의 제조방법에 관한 것으로서, 더욱 상세하게는 동박제조시 구리 전해액에 첨가제를 다수 사용하지 않아도, 내굴곡성이 우수한 이차전지용 전해동박 및 그의 제조방법에 관한 것이다. 본 발명에 따른 이차전지용 전해동박은 TOC(Total organic carbon), 코발트 및 비소가 포함된 도금액에서 드럼을 이용하여 제조되며, 음극활물질이 코팅된 이차전지용 전해동박으로, 상기 전해동박에 함유된 TOC와 코발트 및 비소의 비율은 하기 식 1에 따른다. [식 1] TOC / (코발트+비소) = 1.30 ~ 1.55
