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.

Abstract: An electrode stack is described. The electrode stack may include an anode electrode having an anode current collector, and an anode active material disposed on the anode current collector. The anode electrode may define one or more first apertures through the anode electrode. The electrode stack may also include a cathode electrode having a cathode current collector, and a cathode active material disposed on the cathode current collector. The cathode electrode may define one or more second apertures through the cathode electrode.

Abstract: The disclosed technology relates to a battery pack configured to be structurally mounted to a portable electronic device. The battery pack comprises a plurality of layers and an enclosure. The enclosure comprises a first surface and a plurality of walls that extend from the first surface in a direction perpendicular to the first surface. A portion of the first surface extends past at least one wall of the plurality of walls. The enclosure comprises a second surface configured to be connected to the plurality of walls to form a body configured to enclose the plurality of layers. The portion of the first surface is configured to be coupled to a device and the battery pack is configured to provide at least one component of the device with power when the portion of the first surface is coupled to the device.

Abstract: Battery systems according to embodiments of the present technology may include a battery including a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The battery may define a recessed portion of the battery along the first surface of the battery between the first electrode terminal and the second electrode terminal. The battery systems may include a module electrically coupled with the battery. The module may include a circuit board. The module may include a first conductive tab extending from a second surface of the circuit board opposite the first surface of the circuit board. The first conductive tab may be electrically coupling the module with the first electrode terminal. The module may include a second conductive tab extending from the second surface of the circuit board. The second conductive tab may be electrically coupling the module with the second electrode terminal.
