Abstract
An apparatus and a method for manufacturing a bipolar battery are disclosed, which are capable of restraining the introduction of a bubble, resulting in superior battery performance. A bipolar battery is disclosed for preparing an electrolyte layer, which includes permeable separators such that the electrolytes can penetrate therein and 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. Then, the electrolyte layers are stacked upon one another. When the electrolyte layer is provided to the bipolar electrode, bubbles within the electrolyte layer are exhausted from one side to another side of the separator via the separator.
