    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: Batteries according to embodiments of the present technology may include an electrode stack including a separator positioned between an anode and a cathode. The batteries may include an electrolyte. The batteries may include an enclosure extending about the electrode stack and containing the electrolyte. The enclosure may include a rigid housing defining a volume in which the electrode stack and the electrolyte are contained. The rigid housing may define a flange extending about the rigid housing. The enclosure may include a lid extending across the rigid housing. The lid may be characterized by a length and a width, and the lid may define a protrusion extending beyond the length or width on a side of the lid at a location corresponding to a predetermined strain location.

    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.

    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: Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The housing may include a circumferential indentation proximate the first end. The housing may define a first interior region between the first end and the circumferential indentation, and the housing may define a second interior region between the circumferential indentation and the second end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the second interior region of the housing. The batteries may include a cap at least partially contained within the first interior region of the housing. The batteries may also include a first insulator positioned within the housing. The first insulator may extend across the circumferential indentation from the cap to the set of electrodes.

    Abstract: The disclosed technology relates to an electrical feedthrough for a battery cell. The electrical feedthrough may include a rivet, an outer gasket, an inner gasket, a terminal and an insulator. The rivet compresses the outer gasket, inner gasket, and terminal to create a hermetic seal at an opening through an enclosure of the battery cell. The inner gasket includes a recessed portion for seating of the terminal to prevent rotation of the terminal with respect to the inner gasket, a protrusion for engaging a corresponding notch on the terminal to further prevent rotation of the terminal with respect to the inner gasket, and a mating surface for attaching to the insulator to align and position the insulator within the enclosure. The insulator is positioned between the battery cell and the inner gasket to prevent physical and electrical contact between the set of layers and the feedthrough.
