    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.

    Abstract: A battery can assembly may include the use of insulating adhesive between the can and cover. Because the cover and can are electrically isolated from each other, the respective battery terminals may be directly coupled thereto, eliminating a feed-through to connect electrodes to positive and negative terminals. Such an assembly can eliminate the need for an electrically insulated feed-through. Additionally, welding between the cover and can, which in some cases may be difficult due to shape, size, and or restricted access, may also be eliminated. This can allow for significant simplification of the battery assembly process.
