Kind Code:
A1
Abstract:
A secondary battery according to an embodiment of the present disclosure is characterized by being provided with: a stacked electrode body in which a plurality of electrode plates are stacked with separators interposed therebetween; a plurality of electrode tabs extending from one end of each of the plurality of electrode plates; an outer casing which accommodates the stacked electrode body and which has an opening; a sealing plate for sealing the opening; a current collector which is provided in the sealing plate and which is connected to the plurality of electrode tabs by means of a connecting portion; and a bundling portion bundling the plurality of electrode tabs, between the connecting portion and the stacked electrode body. Adopting such a configuration makes it possible to provide a secondary battery in which damage to the electrode tabs as a result of rubbing between the electrode tabs is suppressed.
