Abstract
Bipolar batteries configured to minimize the introduction of gas bubbles and methods of manufacturing such batteries are taught herein. One bipolar battery includes an electrolyte layer, which includes a plurality of separators having permeability such that the electrolytes can penetrate therein, in a bipolar electrode wherein a cathode is formed at one side of a collector and an anode is formed at another side of the collector. A stack is formed by stacking the electrolyte layers upon one another. The electrolyte layer of the stack has a layer of overlayed separators.
