Abstract: Embodiments described herein relate to electrochemical cells having a separator with a separator seal. In some embodiments, an electrochemical cell includes an anode disposed on an anode current collector, a cathode disposed on a cathode collector, a separator disposed between the anode and the cathode, and a separator seal coupled to the separator. The separator seal is impermeable to the movement of electroactive species therethrough. In some embodiments, the separator seal can include a tape and/or an adhesive. In some embodiments, the separator seal can include a material that permeates into pores of a portion of the separator. In some embodiments, the separator seal can be thermally bonded to the separator. In some embodiments, the electrochemical cell can include a pouch. In some embodiments the separator can be coupled to the pouch. In some embodiments, the separator seal can be coupled to the pouch.

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.
