Abstract
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. The insulator layers are contiguous with the common electrolyte manifold, wherein each of the insulator layers has an anode portion that is directed toward the anode and a cathode portion that is directed toward the cathode, whereby the collector plate exposed end minimizes voltage imbalance of the one cell, the insulator layers minimize short circuiting of the one cell, and the low conductivity electrolyte minimizes leakage currents.
