A device for manufacturing a battery, the device comprising:

a lower die configured to support an electrode;
an upper die above the lower die and connected to the lower die while vertically spaced therefrom;
a lift configured to move the upper die upward or downward;
a punch on the upper die and inserted into the lower die to perform machining of the electrode;

and
a corrector configured to correct a height of the punch according to a control signal of the controller.

5 more elements

A method for manufacturing a battery, the method comprising:

an inputting operation in which an electrode is seated on a lower die;
a measuring operation in which, while an upper die above the lower die moves downward and a punch performs machining of the electrode, a sensor measures a state of the punch;
a monitoring operation in which an insertion amount of the punch according to a thickness of the electrode is calculated according to a detection signal of the sensor and compared with a predetermined value;
and
a correcting operation in which, in a case where the insertion amount of the punch is different from the predetermined value, a corrector corrects a position of the punch so that the insertion amount of the punch reaches the predetermined value.
