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: Embodiments described herein relate generally to devices, systems and methods of producing high energy density electrodes including a first electrode material disposed on a current collector and having a first porosity, and a second electrode material disposed on the first electrode material and having a second porosity less than the first porosity. In some embodiments, the second electrode material includes a mixture of an active material and a conductive material in a liquid electrolyte. In some embodiments, the first electrode materials can have a different composition than the second electrode material. In some embodiments, the first electrode material can include a high-capacity material such as tin, silicon antimony, aluminum, or titanium oxide. In some embodiments, a lithium-containing material can be disposed between the first electrode material and the second electrode material.

Abstract: Embodiments described herein relate generally to apparatuses and processes for forming semi-solid electrodes having high active solids loading by removing excess electrolyte. In some embodiments, the semi-solid electrode material can be formed by mixing an active material and, optionally, a conductive material in a liquid electrolyte to form a suspension. In some embodiments, the semi-solid electrode material can be disposed onto a current collector to form an intermediate electrode. In some embodiments, the semi-solid electrode material can have a first composition in which the ratio of electrolyte to active material is between about 10:1 and about 1:1. In some embodiments, a method for converting the semi-solid electrode material from the first composition into the second composition includes removing a portion of the electrolyte from the semi-solid electrode material. In some embodiments, the method includes mechanically compressing the intermediate electrode to remove the portion of electrolyte from the semi-solid electrode material.

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: A method of manufacturing an electrochemical cell includes transferring an anode semi-solid suspension to an anode compartment defined at least in part by an anode current collector and an separator spaced apart from the anode collector. The method also includes transferring a cathode semi-solid suspension to a cathode compartment defined at least in part by a cathode current collector and the separator spaced apart from the cathode collector. The transferring of the anode semi-solid suspension to the anode compartment and the cathode semi-solid to the cathode compartment is such that a difference between a minimum distance and a maximum distance between the anode current collector and the separator is maintained within a predetermined tolerance. The method includes sealing the anode compartment and the cathode compartment.

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.
