Kaun, T D; Smaga, J A

A bipolar battery is described comprising individual cells with electrode faces in a face-to-face stacked array with electrically opposite electrode ends and electrically conductive end face caps in contact with the electrode ends of the array, each cell including a pair of electrically opposite electrodes in contact with and separated by a central separator containing an electrolyte normally fluid during operation of the battery, the array including a current collector sheet between and in electrical contact with adjacent electrodes of adjacent cells, means for isolating each cell from adjacent cells including a pair of cup-like metallic electrode holders with perforated and facing closed ends in a spaced apart arrangement to enclose the electrodes of the cell with the perforations of each holder permitting an electrode-electrolyte interface for ionic transport, each holder having side walls forming an open end attached in a sealing engagement with an adjacent current collector sheet or end face cap, and an insulating member between and in sealing engagement with the adjacent perforated closed ends to enclose the electrolyte and perforations, and a housing enclosing the array with means for external electrical connection to the electrically opposite ends of the array.
