Abstract
Disclosed are a bipolar battery, a bipolar battery component and a method of manufacturing the same. The bipolar battery minimizes the occurrence of gas bubbles to provide superior battery performance. A battery element has a plurality of bipolar electrodes stacked upon one another while interposing separators therebetween. The bipolar electrode includes a collector formed with a cathode on one surface and an anode on the other surface. The component is a charging part with charging material disposed between collectors and separators to surround at least a periphery of the cathode and a periphery of the anode. An exhaust part is mounted to the charging part to exhaust a residual gas bubble from an inner space to outside of the inner space when stacking the bipolar electrodes.
