Battery systems according to embodiments of the present technology may include a battery cell having an electrode tab extending from an edge of the battery cell. The systems may also include a module electrically coupled with the battery cell. The module may be characterized by a first surface, a height, and a second surface opposite the first surface. A conductive tab coupled along the first surface of the module may extend from a first end parallel to a plane of the first surface. The conductive tab may be characterized by a curvature proximate a midpoint of the conductive tab. A distal region of the conductive tab may return back across the first surface of the module substantially parallel to the first surface. A distal portion of the electrode tab may be fixedly coupled with the distal region of the conductive tab.

Cell packaging techniques

Electrical feedthroughs are presented for redistributing thermally-induced stresses that result from welding. In some embodiments, an electrical feedthrough includes a tubular conduit having a flange at one end. The flange includes a first surface disposed opposite a second surface. The first surface includes at least one of a protrusion and a notch. The electrical feedthrough also includes an electrically-conductive terminal disposed through the tubular conduit. An electrically-insulating material is disposed between the tubular conduit and the electrically-conductive terminal and forms a seal therebetween. The protrusion and the notch are configured individually or as a combination to reduce thermally-induced stresses within the electrically-insulating material that result from welding the flange. Methods for welding such electrical feedthroughs to a wall, such as a wall of a battery housing, are also presented.

Battery assemblies, as well as methods and processes for forming same. A battery assembly can include a first tab electrically connected to a first terminal of a battery and a second tab electrically connected to a second terminal of the battery. A battery assembly can also include a first conductive path (aka first section) having a first end, and a second conductive path (aka second section) having a second end. Another end of the first conductive path can be coupled an electronic device, such as an electric circuit. Another end of the second conductive path can be coupled to the electronic device as well. A space separates the first and second ends; the space formed by removing at least one portion of a U-shaped conductive path. The first conductive path and the first battery tab are connected. The second conductive path and the second battery tab are also connected.
