Abstract
Abstract A battery apparatus is provided which includes a plurality of modules whichre mounted end-to-end in a stacked pile configuration. Each module contains a plurality of bipolar electrodes. One end of each module has a flexible bladder for storing an electrolyte. The bladders in a collapsed condition provide spacing between the modules for cooling. Each module has a passageway for communicating electrolyte from the bladder to the bipolar electrodes. A device seals each passageway from the respective bladder in one mode of operation and is actuated by pressure on the bladder to open the passageway in another mode of operation. With this arrangement pressure on the bladders will distribute electrolyte into each module and the bladders will collapse to provide a cooling space between the modules.
