Abstract
A containment for preventing the flow of liquid electrolyte from one cell electrode to adjacent cell electrodes. The battery being of the type formed of cells stacked in series, each cell having a positive electrode and a negative electrode that contain an electrolyte having a melting point lower than the battery operating temperature. Each cell being separated from an adjacent cell by a respective bipolar wall. The containment is comprised of a salt or salt mixture having a higher melting point than the electrolyte. The containment is placed adjacent the periphery of the cell components and may be provided as a packed powder, a fused or melted segment, or a flexible sleeve containing the higher melting point salt.
