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.

Abstract: The disclosed adjustable strap apparatus may include a left strap having a first rack member and a right strap having a second rack member. An electrical unit may have an opening through which a shaft passes. A pinion member may be affixed to a proximal end of the shaft and may be adapted to (a) engage the first rack member and the second rack member and (b) translate the first rack member and the second rack member in opposite directions via rotation of the shaft. A ratcheting member may be coupled to a distal end of the shaft and may include one or more pawls adapted to prevent rotation of the shaft when engaged.

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.
