Summary: | A method of manufacturing an electrode assembly, according to the present invention, is a method of manufacturing an electrode assembly in which a plurality of electrodes are stacked and comprises: a gripping step in which a gripper grips a unit cell in which a plurality of electrodes and a separator of a predetermined number are stacked; and a static elimination step of exposing the gripper or a unit cell gripped by the gripper to air ions in order to block the generation of static electricity. The manufacturing device of an electrode assembly, according to the present invention, is a manufacturing device of an electrode assembly in which a plurality of electrodes are stacked and comprises: a gripper for gripping a unit cell in which a plurality of electrodes and a separator of a predetermined number are stacked; and an ionizer spraying air ions to the gripper or a unit cell gripped by the gripper. The present invention removes static electricity and removes foreign substances so as to solve the problem of foreign substances sticking to unit cells by static electricity.
본 발명에 따른 전극조립체의 제조방법은, 복수 개의 전극이 적층된 전극조립체를 제조하는 전극조립체의 제조방법에 있어서, 복수 개의 전극과 분리막이 미리 정해진 갯수만큼 적층된 단위셀을 그리퍼가 그립하는 그립단계; 및 정전기 발생을 차단시키기 위해 상기 그리퍼 또는 상기 그리퍼가 그립하는 단위셀을 공기이온에 노출시키는 제전(制電)단계;를 포함한다. 본 발명에 따른 전극조립체의 제조장치는, 복수 개의 전극이 적층된 전극조립체를 제조하는 전극조립체의 제조장치에 있어서, 복수 개의 전극과 분리막이 미리 정해진 갯수만큼 적층된 단위셀을 그립하는 그리퍼; 및 상기 그리퍼 또는 상기 그리퍼가 그립하는 단위셀에 공기이온을 분사하는 이오나이저;를 포함한다. |
