Abstract: Rechargeable battery cells according to embodiments of the present technology may include a housing having a first conductive segment operable at anode potential. The housing may include a second conductive segment operable at cathode potential. The housing may include a gasket positioned between the first conductive segment and the second conductive segment and configured to hermetically seal the housing. The cells may include an electrode stack including an anode. The anode may include an anode tab electrically coupled with the first conductive segment of the housing. The electrode stack may include a cathode. The cathode may include a cathode tab electrically coupled with the second conductive segment of the housing. The cells may include a barrier material disposed between the cathode tab and the second conductive segment of the housing. The cathode tab may be electrically coupled with the second conductive segment of the housing through the barrier material.

Abstract: The disclosed technology relates to a battery utilizing an indicator to orient an unopposed portion of a cathode or anode with respect to a battery can, and a tag to generate an electromagnetic field to mitigate or eliminate an electromagnetic field generated by the unopposed portion of the cathode or anode. The battery includes a wound set of layers including a cathode, an anode, and a separator; a can housing the wound set of layers; a lid disposed atop of the can to enclose the wound set of layers within the can; and a tag coupled to the lid. An unopposed portion of the cathode or anode generates a first electromagnetic field. The tag generates a second electromagnetic field to oppose the first electromagnetic field.

Abstract: The disclosed technology relates to an electrical feedthrough for a battery cell. The electrical feedthrough may include a pin configured to form an external battery terminal, an insulator surrounding the pin and configured to electrically isolate the pin, a channel, and a serpentine tab electrically coupled to the pin at a first end. The serpentine tab is nested within the channel to minimize use of space within an enclosure of the battery cell thereby increasing energy capacity of the battery cell by eliminating the need to allot space within the enclosure to accommodate the tab.
