Zusammenfassung:An electrode rolling apparatus according to an embodiment of the present invention is an apparatus for rolling an electrode substrate having a coated part and an uncoated part, and comprises: a coil part having an effective area in which a uniform magnetic field is generated; and an electrode rolling unit that rolls the electrode substrate. The coated part and the uncoated part each include a plurality of pattern portions. The uncoated part includes: first uncoated pattern portions located at one or both ends of the electrode substrate; and second uncoated pattern portions located between adjacent coated pattern portions. The coil part includes: a first coil part that heats the first uncoated pattern portions; and a second coil part that heats the second uncoated pattern portions. The heating temperature of the second coil part is lower than the heating temperature of the first coil part. Un appareil de laminage d'électrode selon un mode de réalisation de la présente invention est un appareil pour laminer un substrat d'électrode ayant une partie revêtue et une partie non revêtue, et comprend : une partie bobine ayant une zone efficace dans laquelle un champ magnétique uniforme est généré ; et une unité de laminage d'électrode qui roule le substrat d'électrode. La partie revêtue et la partie non revêtue comprennent chacune une pluralité de parties de motif. La partie non revêtue comprend : des premières parties de motif non revêtues situées à une extrémité ou aux deux extrémités du substrat d'électrode ; et des secondes parties de motif non revêtues situées entre des parties de motif revêtues adjacentes. La partie de bobine comprend : une première partie de bobine qui chauffe les premières parties de motif non revêtues ; et une seconde partie de bobine qui chauffe les secondes parties de motif non revêtues. La température de chauffage de la seconde partie de bobine est inférieure à la température de chauffage de la première partie de bobine. 본 발명의 일 실시예에 따른 전극 압연 장치는 코팅부와 미코팅부를 갖는 전극 기재를 압연하는 장치에 있어서, 균일한 자기장이 발생하는 유효 영역을 갖는 코일부, 및 상기 전극 기재를 압연하는 전극 압연부를 포함하고, 상기 코팅부와 상기 미코팅부는 각각 복수의 패턴부를 포함하고, 상기 미코팅부는 상기 전극 기재의 양 단부 중 적어도 일 단부에 위치하는 제1 미코팅 패턴부 및 서로 이웃하는 코팅 패턴부 사이에 위치하는 제2 미코팅 패턴부를 포함하며, 상기 코일부는, 상기 제1 미코팅 패턴부를 가열하는 제1 코일부와, 상기 제2 미코팅 패턴부를 가열하는 제2 코일부를 포함하고, 상기 제2 코일부의 가열 온도는 상기 제1 코일부의 가열 온도보다 낮다.
