  • Publication number: 20170092923
    Abstract: Battery cells are presented that have notched electrodes. In one embodiment, the battery cells have a first notch in an electrode and a second notch in a seal. The second notch allows a first portion of the seal adjacent the first edge to fold without overlapping a second portion of the seal adjacent the second edge. The first notch serves as a relief zone that enables the seal to maintain a seal distance during folding. In another embodiment, the battery cells have a first notch in an electrode and a second notch in a portion of a separator. The first notch and the second notch, in combination, allow the separator to fold along a fold line without tearing. Other battery cells are presented.

  • Publication number: 20160293995
    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.

  • Publication number: 20150263378
    Abstract: The disclosed embodiments relate to the design and manufacture of a battery cell. The battery cell includes a jelly roll containing layers which are wound together, including a cathode with an active coating, a separator, and an anode with an active coating. The battery cell also includes a mechanical structure disposed around a perimeter of the jelly roll to maintain a structural integrity of the jelly roll. Finally, the battery cell includes a pouch enclosing the mechanical structure and the jelly roll, wherein the pouch is flexible.
