    Abstract: Embodiments described herein relate generally to electrochemical cells having dual electrolytes, systems of such electrochemical cells, and methods for manufacturing the same. In some embodiments, electrochemical cells can include a cathode disposed on a cathode current collector, an anode disposed on an anode current collector, and a separator disposed therebetween. In some embodiments, the separator can include materials that fluidically and/or chemically isolate the anode from the cathode. In some embodiments, the cathode and/or anode can include a slurry of an active material and a conductive material in a liquid electrolyte. In some embodiments, the anode can be fluidically coupled to an anode degassing port. In some embodiments, the cathode can be fluidically coupled to a cathode degassing port.

    Abstract: Electrochemical cells and methods of making electrochemical cells are described herein. In some embodiments, an apparatus includes a multi-layer sheet for encasing an electrode material for an electrochemical cell. The multi-layer sheet including an outer layer, an intermediate layer that includes a conductive substrate, and an inner layer disposed on a portion of the conductive substrate. The intermediate layer is disposed between the outer layer and the inner layer. The inner layer defines an opening through which a conductive region of the intermediate layer is exposed such that the electrode material can be electrically connected to the conductive region. Thus, the intermediate layer can serve as a current collector for the electrochemical cell.

    Abstract: Apparatus, systems, and methods described herein relate to safety devices for electrochemical cells comprising an electrode tab electrically coupled to an electrode, the electrode including an electrode material disposed on a current collector. In some embodiments, a fuse can be operably coupled to or formed in the electrode tab. In some embodiments, the fuse can be formed by removing a portion of the electrode tab. In some embodiments, the fuse can include a thin strip of electrically resistive material configured to electrically couple multiple electrodes. In some embodiments, the current collector can include a metal-coated deformable mesh material such that the current collector is self-fusing. In some embodiments, the fuse can be configured to deform, break, melt, or otherwise discontinue electrical communication between the electrode and other components of the electrochemical cell in response to a high current condition, a high voltage condition, or a high temperature condition.

    Abstract: An automotive or other power system including a flow cell, in which the stack that provides power is readily isolated from the storage vessels holding the cathode slurry and anode slurry (alternatively called “fuel”) is described. A method of use is also provided, in which the “fuel” tanks are removable and are separately charged in a charging station, and the charged fuel, plus tanks, are placed back in the vehicle or other power system, allowing fast refueling. The technology also provides a charging system in which discharged fuel is charged. The charged fuel can be placed into storage tanks at the power source or returned to the vehicle. In some embodiments, the charged fuel in the storage tanks can be used at a later date. The charged fuel can be transported or stored for use in a different place or time.
