  • Electrochemical System Having a System for Determining a State of Charge
    Publication number: 20130029185
    Abstract: An electrochemical system, such as a flow battery, includes a vessel. The vessel contains at least one cell that includes a first electrode, a second electrode and a reaction zone between the first and second electrodes. The vessel also contains a flow circuit configured to deliver a fluid comprising a liquefied halogen reactant and at least one metal halide electrolyte to the at least one cell, and at least one sensor configured to measure a property of the electrochemical system indicative of a state of charge (SOC) of the electrochemical system.

  • Metal electrode assembly for flow batteries
    Patent number: 8202641
    Abstract: A flow battery electrode assembly with a first impermeable, substantially metal electrode, a second permeable, substantially metal electrode and at least one electrically conductive spacer. The electrically conductive spacer connects the first impermeable, substantially metal electrode and the second permeable, substantially metal electrode such that the first impermeable, substantially metal electrode and the second permeable, substantially metal electrode are spaced apart from each other by an electrolyte flow path.
