Beschreibung
Zusammenfassung:	An electrode tab bending method for solving the above problem, according to an embodiment of the present invention, comprises the steps of: stacking electrodes and separators together to manufacture an electrode assembly; connecting electrodes leads to electrode tabs which are formed to protrude from the electrode assembly; primarily bending the electrode tabs by moving a bending block, disposed on one side of the electrode tabs, in a first direction toward the other side of the electrode tabs; and secondarily bending the electrode tabs by moving the bending block in a second direction different from the first direction. Selon un mode de réalisation, la présente invention concerne un procédé de pliage de languette d'électrode permettant de résoudre le problème ci-dessus et consistant à : empiler des électrodes et des séparateurs ensemble pour fabriquer un ensemble d'électrodes ; connecter des fils d'électrode à des languettes d'électrode qui sont formées pour faire saillie à partir de l'ensemble d'électrodes ; plier en premier lieu les languettes d'électrode par déplacement d'un bloc de pliage, disposé sur un côté des languettes d'électrode, dans une première direction vers l'autre côté des languettes d'électrode ; et plier en second lieu les languettes d'électrode par déplacement du bloc de pliage dans une seconde direction différente de la première direction. 상기 과제를 해결하기 위한 본 발명의 실시예에 따른 전극 탭 절곡 방법은 전극 및 분리막을 적층하여 전극 조립체를 제조하는 단계; 상기 전극 조립체로부터 돌출 형성된 전극 탭에 전극 리드를 연결하는 단계; 상기 전극 탭의 일측에 배치된 절곡 블록이, 타측을 향하는 제1 방향으로 이동하여 상기 전극 탭을 1차 절곡하는 단계; 및 상기 절곡 블록이 상기 제1 방향과 상이한 제2 방향으로 이동하여 상기 전극 탭을 2차 절곡하는 단계를 포함한다.
