ABSTRACT:
An injection molded containment for bipolar batteries of the type which include terminal electrodes and one or more bipolar battery cells is disclosed. In the most preferred embodiment of the present invention, a novel spacer is employed, including beveled edges to facilitate sealing of the injection molding material and the individual cells. Furthermore, the preferred spacer includes a crush ridge to assist in sealing. The present invention facilitates assembly of bipolar batteries in a way which improves sealing when compared to other techniques, such as vibration welding.
