Abstract: A non-cuboidal battery having a cross-sectional area and a thickness may include a metal can housing, a metal lid coupled to the metal can housing, and an electrode stack disposed in the metal can housing. The thickness of the non-cuboidal battery can be substantially uniform over the cross-sectional area. The electrode stack may include a cathode layer stacked on an anode layer, and a separator layer disposed between the cathode layer and the anode layer. The electrode stack may be hermetically sealed by the metal can housing and the metal lid. A negative terminal that can be electrically coupled to the anode layer and a positive terminal that can be electrically coupled to the cathode layer may be disposed on an exterior side of the metal can housing or the metal lid.

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.
