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: The disclosed technology relates to a battery pack configured to be structurally mounted to a portable electronic device. The battery pack may comprise an enclosure configured to enclose a plurality of layers. One or more primary brackets may be connected to at least one wall of the enclosure. Each of the one or more primary brackets may be configured to be coupled to a device. The battery pack may be configured to provide at least one component of the device with power when the one or more primary brackets are coupled to the device. A protector may be interposed between at least one of the one or more primary brackets and the at least one wall of the enclosure. The protector may be configured to provide a layer of protection between the at least one primary bracket and the plurality of layers.

Abstract: An electronic enclosure includes walls that extend crosswise from one another to define a portion of an internal volume of the electronic enclosure. The walls extend from one another via an interface formed between the walls. The interface includes a notch, such as an arcuate portion, configured to concentrate stress caused by pressure buildup within the internal volume such that an amount of stress at the notch is greater than an amount of stress at other portions of the electronic enclosure.
