Abstract

An improved electrolyte circulation subsystem which reduces and minimizes the effect of parasitic currents in secondary batteries having a plurality of cells connected electrically in series and a common electrolyte in communication with the cells is described. The improved electrolyte circulation subsystem includes means for pumping an electrolyte, and manifold means for conveying electrolyte to a plurality of cells connected electrically in series. The manifold means generally comprises an outer tube formed with an outlet port at each end thereof, and an inner tube concentrically disposed within the outer tube generally along one-half of the outer tube length. The inner tube is in fluid communication with the pumping means at a first end thereof and is in fluid communication with the outer tube at a second end thereof. The inner tube also has means associated with the second end for generally equally diverting the flow of the electrolyte through the inner tube to each of the outlet ports of the outer tube. The electrolyte circulation subsystem also includes a separate conduit means in fluid communication with each of the outlet ports of the outer tube for individually distributin…
