Abstract
A device for determining whether or not positive and negative electrode tabs constituting an electrode assembly are bent includes: a stably nesting portion in which the electrode assembly is stably nested; an electrode tab contact portion arranged on a side surface of the stably nesting portion and configured to move downward so as to come into contact with one end portion of an electrode tab, bending the electrode tab, and to elastically restore the electrode tab to an original state thereof; a weight measurement unit arranged above the stably nesting portion and configured to measure, on a per-area basis, a weight of the electrode tab that is elastically restored to an original state thereof; and a determination unit configured to determine whether or not the electrode tab is bent, depending on an area where the weight is measured.
