Abstract: An example augmented-reality headset comprises a frame portion, a temple arm portion coupled with the frame portion, and a metal-encased battery cell having an exterior surface that defines a non-rectangular shape. The metal-encased battery cell is configured to be housed within the temple arm portion, and the non-rectangular shape of the exterior surface follows an interior shape of an internal surface of the temple arm portion. The augmented-reality headset also comprises one or more artificial-reality processing or presentation devices, wherein at least one of the one or more artificial-reality processing or presentation devices is configured to receive power from the metal-encased battery cell.

Abstract: Can battery cells are described. The can battery cell includes a battery cell core that is housed in a rigid enclosure. The enclosure can be made of metal or other rigid material. A front face of the enclosure includes an anode tab and a cathode tab extending from the front face. A circuit module is electrically coupled to the anode tab and the cathode tab, and overlies at least a portion of the front face of the enclosure. One of the anode tab or the cathode tab is electrically coupled to the battery enclosure. The other of the anode tab or the cathode tab is electrically insulated from the enclosure. The front face includes a protrusion portion that forms a step-like structure in the front face of the enclosure.
