Abstract: The disclosed technology relates to electrical feedthroughs for thin battery cells. A battery cell enclosure includes a terraced portion having a reduced thickness relative to another portion of the enclosure. The enclosure includes an opening disposed on a horizontal surface of the terraced portion for receiving the electrical feedthrough. Because the feedthrough is disposed on the horizontal surface of the terraced portion, the feedthrough may be over-sized thereby reducing the resistance and impedance of the feedthrough without increasing the height or thickness of the enclosure.

Abstract: The disclosed embodiments relate to the design of a jelly-roll battery comprising an alternating anode and cathode layers coated with intervening separator layers wound into a jelly-roll. The alternating anode and cathode layers are coated with, respectively, an anode active coating and a cathode active coating. A first common notch and a second common notch are formed along at least one side of the jelly-roll. A common cathode tab can be bonded to the cathode tabs within the first common notch, and a common anode tab can be bonded to the anode tabs within the second common notch. The jelly-roll battery also includes a pouch enclosing the jelly-roll. Common anode and cathode tabs can extend through the pouch to provide cathode and anode terminals for the battery cell.

Abstract: Aspects of the present disclosure involve various battery can designs. In general, the battery can design includes two fitted surfaces oriented opposite each other and seam welded together to form an enclosure in which a battery stack is located. To form the enclosure, the two fitted surfaces are welded together along the large perimeter. Other swelling-resisting advantages may also be achieved utilizing the battery can design described herein including, but not limited to, the ability to modify one or more can wall thicknesses to control a pressure applied to the battery stack by the can, overall reduction in wall thickness of the can through the use of stronger materials for the can surfaces, additional supports structures included within the can design, and/or bossing or other localized thinning of surfaces of the can.
