Bipolar battery and assembly method.

摘要

The specification discloses a bipolar battery and a method of making intercell connections between adjacent cells thereof including a container (100) having an intercell partition (108) a section (109) of which is thicker than the remainder of the partition (108). The thickened section (109) has an opening (114) therethrough receiving intercell connector links (124), which opening (114) has a mouth (135,137) at each end thereof confronting a respective one of a set of adjacent cell compartments (110,112). Barriers (134) are provided contiguous the mouths (135,137) of the opening (114) and define therebetween a region (116) in the opening (114) for receiving sealant (136) injected thereinto. The barriers (134) confine the sealant (136) to the region (116) and prevent it from exuding into the adjacent cell compartments (110,112). In one embodiment, the barriers comprise rails moulded onto the bipolar electrodes. In another embodiment, the barriers comprise compressed glass-fibre mats (134).
