ABSTRACT:
An improved battery of the type formed of cells stacked in series. The positive and negative electrodes of each cell being separated by a separator and each cell being separated by a respective bipolar wall. A sleeve-like seal is provided around the periphery of each cell. The seal is preferably made of a nonwettable material that can be made in a flexible form, such as boron nitride. The barrier seal being in sealing contact with opposed planar faces of bipolar walls bounding each cell. The seal is preferably affixed to the bipolar walls by a paintable cement made of a mixture of boron nitride powder and a clay binder suspended in a nonaqueous organic vehicle.
