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 dispensation of semi-solid electrode material. In some aspects a method of forming an electrode ribbon can include dispensing an entry stream of semi-solid electrode material into a nozzle, while the entry stream is in the nozzle, dividing the entry stream into a first substream and a second substream, while the first substream and the second substream are in the nozzle, rejoining the first substream and the second substream to form a rejoined stream, dispensing the rejoined stream out of the nozzle onto a current collector via an orifice to form an electrode ribbon. In some embodiments, the dividing can be via a rib disposed along an interior surface of the nozzle. In some embodiments, the entry stream can be divided into a first substream, a second substream, and a third substream.
