Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The housing may include a circumferential indentation proximate the first end. The housing may define a first interior region between the first end and the circumferential indentation, and the housing may define a second interior region between the circumferential indentation and the second end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the second interior region of the housing. The batteries may include a cap at least partially contained within the first interior region of the housing. The batteries may also include a first insulator positioned within the housing. The first insulator may extend across the circumferential indentation from the cap to the set of electrodes.

Abstract: An outer cover of a pouch-style battery includes a nanoceramic coating. Constructing an outer cover including a nanoceramic coating may include forming a malleable layer, applying a sealing layer to an inside surface of the malleable layer, and applying the nanoceramic layer to an outside surface of the malleable layer. Fabricating an outer cover including a nanoceramic coating may further include applying a protective film to an outside surface of the outer cover, which may be removed shortly before or after installation of a battery cell for which the outer cover is manufactured. Fabricating an outer cover including a nanoceramic coating may also include applying one or more adhesive layers, for example an adhesive layer between the malleable layer and the sealing layer. An outer cover including a nanoceramic coating may be sealed around a battery-active-material assembly to form a pouch-style battery cell.

Abstract: Energy storage devices, battery cells, and batteries of the present technology may include a housing characterized by a first end and a second end opposite the first end. The batteries may include a set of electrodes located within the housing. The set of electrodes may be positioned within the interior region of the housing. The set of electrodes may include a first electrode and a second electrode. The first electrode may include a tab coupled with a surface of the housing at a distal end and coupled with the first electrode at a proximal end. The tab may be coupled with a first surface of the first electrode. A first insulating material may be applied along a second surface of the first electrode across a section corresponding to a location where the tab is coupled with the first electrode. The batteries may also include a cap at least partially contained within the interior region of the housing. The cap may be characterized by a first surface facing the set of electrodes.

Abstract: Electrical feedthroughs for battery housings are presented. The electrical feedthroughs include a connector, a ceramic insulator, and a terminal. A first seal couples the connector to the ceramic insulator via a first braze alloy. A second seal couples the ceramic insulator to the terminal via a second braze alloy. The electrical feedthroughs can also include a spacer. A first seal couples the connector to the ceramic insulator; a second seal couples the ceramic insulator to the spacer; and the third seal couples the spacer to the terminal. The first seal, the second seal, and the third seal include, respectively, a first braze alloy, a second braze alloy, and a third braze alloy.

Abstract: Aspects of the present disclosure involve various battery can designs. In general, the battery can design includes two fitted surfaces oriented opposite each other and seam welded together to form an enclosure in which a battery stack is located. To form the enclosure, the two fitted surfaces are welded together along the large perimeter. Other swelling-resisting advantages may also be achieved utilizing the battery can design described herein including, but not limited to, the ability to modify one or more can wall thicknesses to control a pressure applied to the battery stack by the can, overall reduction in wall thickness of the can through the use of stronger materials for the can surfaces, additional supports structures included within the can design, and/or bossing or other localized thinning of surfaces of the can.
