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.
