Battery systems according to embodiments of the present technology may include a battery including a lid that defines lateral dimensions of the battery and a base. The base may define an internal volume of the battery between an interior surface of the lid and an interior surface of the base. The base may be coupled with the lid to define a flange extending about lateral edges of the battery. The base may define a tiered profile along an exterior surface of the battery towards a first lateral edge of the battery. The tiered profile may include a first tier defining a depth of the battery, a second tier defining a first terrace proximate the flange along an intersection of the first lateral edge of the battery and a second lateral edge of the battery, and a third tier extending inward from the first lateral edge of the battery and extending between the first terrace and the second terrace. A battery may also include a module seated on the exterior surface of the base of the battery along the third tier, and between the first terrace and the second terrace.

Thin battery pack architecture

The disclosed technology relates to electrical feedthroughs for thin battery cells. A battery cell enclosure includes a terraced portion having a reduced thickness relative to another portion of the enclosure. The enclosure includes an opening disposed on a horizontal surface of the terraced portion for receiving the electrical feedthrough. Because the feedthrough is disposed on the horizontal surface of the terraced portion, the feedthrough may be over-sized thereby reducing the resistance and impedance of the feedthrough without increasing the height or thickness of the enclosure.

Feedthroughs for thin battery cells

Battery systems according to embodiments of the present technology may include a battery characterized by a first surface, a second surface, and a third surface. A recessed ledge may be defined by the third surface about a midpoint of the battery. The first surface and the third surface may define a first terrace formed proximate a first lateral edge of the first surface of the battery adjacent the third surface of the battery, and a second terrace formed proximate a second lateral edge of the first surface of the battery adjacent the third surface of the battery and opposite the first lateral edge. The recessed ledge may extend along the first surface of the battery between the first terrace and the second terrace. The battery systems may also include a module seated on the first surface of the battery between the first terrace and the second terrace.
