Abstract: A reserve battery cell which includes a battery cell housing, an anode and cathode collector, and a reservoir housing which includes a quantity of electrolyte which, when applied to the anode and cathode collector, cause the battery to generate an electric current through an external load. Burst discs are located proximate the extremities of the reservoir housing. The upstream burst disc is capable of rupturing upon the application of sufficient externally applied pressure while the downstream burst disc is capable of rupturing upon the application of sufficient hydraulic pressure exerted thereon by the electrolyte. The piston is located within the reservoir housing which establishes the upstream boundary of the electrolyte and which is capable of traveling down the reservoir housing upon the application of an externally applied pressure and which is characterized as preventing electrolyte from leaking around the piston and any substantial amount of gas from entering the electrolyte through the piston body.

Abstract: A common electrolyte manifold battery that includes at least one module having a plurality of cells, at least one common electrolyte manifold traversing the cells for transporting a low conductivity electrolyte, an anode and a cathode. The one module includes a collector plate, the collector plate has an end exposed to the common electrolyte manifold, and one of the cells. The one cell comprises a first bipolar plate, positioned in parallel with the collector plate, that has an end proximal to the manifold and an end distal to the manifold, the distal end being connected to the anode. In addition, a second bipolar plate is provided, positioned parallel with the anode plate, that has an end proximal to the manifold and an end distal to the manifold, the distal end being connected to the cathode. The one cell further comprises a layer of insulator enveloping each of the proximal end of the first bipolar plate and the second bipolar plate.
