  • Patent number: 4091184
    Abstract: A high rate rechargeable silver-zinc pile type battery including a plurality of bipolar electrodes which are assembled into a full scale multi-cell pile. Each of bipolar electrodes includes a positive side having a porous silver matrix attached to silver foil and a negative side having a porous zinc structure vapor deposited on silver foil. A separator including three different components in layers is disposed between the positive and negative sides of the bipolar electrode. An epoxy adhesive is used to position and retain a seal in its proper location to electrically isolate the individual electrodes and form a cavity for retention of the electrolyte. Intercell connectors of etched silver foil serve as the cell case and active material substrate as well as the series connection between individual cells for electrical continuity.
