  • Publication number: 20210320285
    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.

  • Publication number: 20210074958
    Abstract: This application relates to a battery system for reducing spacing between components in an electronic device. The battery system includes a housing surrounding an electrode assembly and a connection module. The housing is rigid or semi-rigid and connected to a common ground. The battery system can be positioned in the electronic device to contact components without damaging the components. In some embodiments, the battery system can be used as a structural element in the electronic component.

  • Publication number: 20200403210
    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.
