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: 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。
