Abstract:
Embodiments of a battery taught herein are directed to preventing a displacement between bipolar battery stacks or between a bipolar battery stack and an electrode tab. A bonding portion is formed at a part of a contact surface where a collector positioned at both ends in a stacking direction of a bipolar battery stack is bonded to the electrode tabs. The electrode tab and the collector are fixed by such a bonding portion. Further, the bonding portion is formed at a part of a contact surface where adjacent bipolar battery stacks are bonded to each other. Bipolar batteries positioned at upper and lower portions in the stacking direction are fixed by such a bonding portion.
