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: Embodiments described herein relate generally to electrochemical cells having semi-solid electrodes that include a gel polymer additive such that the electrodes demonstrate longer cycle life while significantly retaining the electronic performance of the electrodes and the electrochemical cells formed therefrom. In some embodiments, a semi-solid electrode can include about 20% to about 75% by volume of an active material, about 0.5% to about 25% by volume of a conductive material, and about 20% to about 70% by volume of an electrolyte. The electrolyte further includes about 0.01% to about 1.5% by weight of a polymer additive. In some embodiments, the electrolyte can include about 0.1% to about 0.7% of the polymer additive.

Abstract: Embodiments described herein relate generally to electrochemical cells including a selectively permeable membrane and systems and methods for manufacturing the same. In some embodiments, the selectively permeable membrane can include a solid-state electrolyte material. In some embodiments, electrochemical cells can include a cathode disposed on a cathode current collector, an anode disposed on an anode current collector, and the selectively permeable membrane disposed therebetween. 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, a catholyte can be different from an anolyte. In some embodiments, the catholyte can be optimized to improve the redox electrochemistry of the cathode and the anolyte can be optimized to improve the redox electrochemistry of the anode. In some embodiments, the selectively permeable membrane can be configured to isolate the catholyte from the anolyte.

Abstract: Embodiments described herein relate to electrochemical cells with multiple separators, and methods of producing the same. A method of producing an electrochemical cell can include disposing an anode material onto an anode current collector, disposing a first separator on the anode material, disposing a cathode material onto a cathode current collector, disposing a second separator onto the cathode material, and disposing the first separator on the second separator to form the electrochemical cell. The anode material and/or the cathode material can be a semi-solid electrode material including an active material, a conductive material, and a volume of liquid electrolyte. In some embodiments, less than about 10% by volume of the liquid electrolyte evaporates during the forming of the electrochemical cell. In some embodiments, the method can further include wetting the first separator and/or the second separator with an electrolyte solution prior to coupling the first separator to the second separator.

Abstract: Embodiments described herein relate to semi-solid electrodes with carbon additives, and methods of making the same. In some embodiments, a semi-solid electrode, can include about 35% to about 75% by volume of an active material, about 0.5% to about 8% by volume of a conductive material, and about 0.2% to about 5% by volume of a carbon additive. The carbon additive is different from the conductive material. The active material, the conductive material, and the carbon additive are mixed with a non-aqueous electrolyte to form the semi-solid electrode. In some embodiments, the carbon additive includes carbon nanofibers, vapor-grown carbon fibers (VCGF), carbon nanotubes (CNT's), single-walled carbon nanotubes (SWNT's), and/or multi-walled carbon nanotubes (MWNT's).
