Abstract: Embodiments described herein relate generally to systems and methods for continuously and/or semi-continuously manufacturing electrochemical cells with semi-solid electrodes. In some embodiments, a method can include mixing an active material, a conductive material, and an electrolyte to form a semi-solid electrode material. The method further includes drawing a vacuum on the semi-solid electrode material, compressing the semi-solid electrode material to form an electrode brick, and dispensing a portion of the electrode brick onto a current collector via a dispensation device to form an electrode. In some embodiments, the current collector is disposed on a pouch material. In some embodiments, the dispensation device includes a top blade for top edge control and two side plates for side edge control. In some embodiments, the method can further include conveying the electrode through the top blade and the two side plates to shape the electrode.

Abstract: Embodiments described herein relate to recycling of electrochemical cell materials. In some aspects, a method can include separating a stack pouch material from an electrochemical cell stack, separating a plurality of unit cells from the electrochemical cell stack into individual unit cells, cutting within a heat seal of a cell pouch of a unit cell from the plurality of unit cells, separating a cathode material and a cathode current collector away from a separator, an anode material, and an anode current collector of the unit cell, placing the cathode material and the cathode current collector in a solvent bath with the cathode current collector facing downward, separating the cathode material from the cathode current collector via an ultrasonic probe, separating solids and liquids of the cathode material, drying the solids of the cathode material, and incorporating the solids of the cathode material into a new cathode mixture.
