    Abstract: Battery systems according to embodiments of the present technology may include a battery. The battery may include a first electrode terminal and a second electrode terminal accessible along a first surface of the battery. The systems may include a module electrically coupled with the battery. The module may include a circuit board characterized by a first surface and a second surface opposite the first surface. The module may include a mold extending from the first surface of the circuit board toward the battery. The module may include a first conductive tab electrically coupling the module with the first electrode terminal. The module may include a second conductive tab electrically coupling the module with the second electrode terminal. The second conductive tab may extend across the mold substantially parallel to the first surface of the circuit board.

    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.

    Abstract translation: 本公开的方面涉及各种电池罐设计。 通常，电池可以设计包括彼此相对定向并且被焊接在一起的两个装配表面，以形成电池堆所在的外壳。 为了形成外壳，两个装配的表面沿着大的周边焊接在一起。 还可以利用本文所述的电池罐设计来实现其它抗膨胀的优点，包括但不限于修改一个或多个罐壁厚度以控制通过罐施加到电池堆的压力的能力，整体减小壁 罐的厚度通过使用用于罐表面的更坚固的材料，包括在罐设计内的附加支撑结构，和/或罐的表面的凸起或其它局部变薄。

    Abstract: Electrical feedthroughs are presented that are integrated within a wall of a battery housing. In some embodiments, an electrical feedthrough includes a battery housing defining an opening. The electrical feedthrough also includes a collar disposed around the opening and forming a single body with the wall. The electrical feedthrough also includes an electrically-conductive terminal disposed through the collar. The electrical feedthrough additionally includes an electrically-insulating material disposed between the collar and the electrically-conductive terminal and forming a seal therebetween. In some embodiments, the wall has a thickness equal to or less than 1 mm. In some embodiments, the collar protrudes into the battery housing. In other embodiments, the collar protrudes out of the battery housing. In some embodiments, a cross-sectional area of the electrically-conductive terminal is at least 40% of an area bounded by an outer perimeter of the collar. Batteries incorporating the electrical feedthroughs are also presented.

    Abstract: The disclosed technology relates to an electrical feedthrough for a cylindrical battery cell. The electrical feedthrough may include an annular channel having an outer sidewall, an inner sidewall, and a base; an insulator formed of glass having an overmold portion; and a pin extending through the insulator and configured to form an external battery terminal. The insulator is bonded to the inner sidewall of the annular channel and a portion of the base of the annular channel. The overmold portion prevents electrical contact between a set of electrodes and the electrode feedthrough.
