ABSTRACT:
Bipolar battery and method of making intercell connections between adjacent cells thereof including a container having an intercell partition a section of which is thicker than the remainder of the partition. The thickened section has an opening therethrough receiving the intercell connectors, which opening has a mouth at each end thereof confronting one of a set of adjacent cell compartments. Barriers are provided contiguous the mouths of the opening and define therebetween a region in the opening for receiving sealant injected thereinto. The barriers confine the sealant to the region and prevent it from exuding into the adjacent cell compartments. In one embodiment, the barriers comprise rails molded onto the bipolar electrodes. In another embodiment, the barriers comprise compressed glass mats.
