Patent ID: 8470469

Claim:
A method for manufacturing a bipolar battery, the method comprising: providing positive electrodes, separators, negative electrodes and at least one biplate to construct a plurality of battery cells inside a case, arranged between a positive endplate and a negative endplate; providing a positive access point to the positive endplate, and a negative access point to the negative endplate; providing a gasket in the shape of a frame and arranged at least one of between each biplate or between a biplate and an endplate, the gasket at least partially encompassing a peripheral surface of the biplate, the gasket including a gas channel extending between adjacent battery cells to create a common gas space defined within the battery cells and the gas channel of each gasket, wherein the common gas space does not extend outside of the gasket and into a space existing between the gasket and the case; providing a passage to the common gas space from the outside of the battery; compressing all gaskets arranged between the positive endplate and the negative endplate to provide an outer pressure tight seal for the battery and to prevent the formation of electrolyte paths between adjacent cells; and filling the separators with electrolyte.
