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: 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: Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing semi-solid electrodes and batteries incorporating semi-solid electrodes. In some embodiments, the process of manufacturing a semi-solid electrode includes continuously dispensing a semi-solid electrode slurry onto a current collector, separating the semi-solid electrode slurry into discrete portions, and cutting the current collector to form a finished electrode.

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: Apparatus, systems, and methods described herein relate to the manufacture and use of single pouch battery cells. In some embodiments, an electrochemical cell includes a first current collector coupled to a first portion of a pouch, the first current collector having a first electrode material disposed thereon, a second current collector coupled to a second portion of the pouch, the second current collector having a second electrode material disposed thereon, and a separator disposed between the first electrode material and the second electrode material. The first portion of the pouch is coupled to the second portion of the pouch to enclose the electrochemical cell.
