A battery system includes a battery cell, a thermally insulating layer, and a thermally conducting layer which includes a fin. The fin pushes against an interior surface of a case which surrounds the battery cell, the thermally insulating layer, and the thermally conducting layer. The thermally conducting layer includes a discontinuity where the discontinuity is configured to reduce a capacitance associated with the thermally conducting layer compared to when the thermally conducting layer does not include the discontinuity.

Capacitance reduction in battery systems

Various embodiments of a technique are provided for determining the quality of a weld for a battery contact using audio signals. In some embodiments, a system for determining the quality of a weld for a battery contact comprises a processor configured to receive a snapshot that includes a rendering of an audio signal obtained during a welding process by monitoring a device being welded. A weld-quality indicator for the device being welded is determined based at least in part on features extracted from the snapshot and a weld-quality score for the device being welded is determined in response to the weld-quality indicator. In this case, the weld-quality score is indicative of a quality of the weld. The system also includes a memory coupled to the processor and configured to provide the processor with instructions.
