摘要:
When a bipolar battery is manufactured, a bipolar electrode and a separator are prepared first. Then, one electrode (for example, a positive electrode) out of positive and negative electrodes is applied with such an amount of electrolyte as being exposed on a surface of the one electrode. Then, the separator is arranged on the surface of the one electrode applied with the electrolyte, thus forming a sub-assembly unit. Then, a plurality of the sub-assembly units are layered, and the electrolyte applied to the one electrode is made to permeate through the separator to the other electrode, thus forming an assembly unit.

A battery structure for improving a heat dissipating property and a vibration absorbing performance. The battery structure comprises a plurality of unit cell layers, each formed by alternately stacking a cathode active material layer formed on a surface of one collector, a separator for retaining an electrolyte and an anode active material layer formed on a surface of another collector. The battery structure also comprises a heat dissipating member disposed between at least one unit cell layer and another unit cell layer.

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.
