Abstract: A prismatic lithium ion battery cell includes a packaging having a cover. The cover includes: a first spiral disk feature disposed below a first terminal pad; a second spiral disk feature disposed below a second terminal pad; a first reversal disk disposed below the first spiral disk feature; and a second reversal disk disposed below the second spiral disk feature. The first and second reversal disks are configured to deflect upwards to displace the first and second spiral disk features to contact the first and second terminal pads, respectively, in response to a pressure within the packaging being greater than a predefined pressure threshold and form an external short-circuit between the first and second terminal pads via the first and second spiral disk features. Subsequently, a portion of the power assembly fails in response to the external short-circuit and interrupts current flow between the first and second terminal pads.

Abstract: A battery module includes a battery module housing, a heat exchanger including a plurality of fins disposed in the housing, a first lithium ion battery cell and a second lithium ion battery cell disposed within the battery module housing. The first lithium ion battery cell and the second lithium ion battery cell are separated by a fin of the plurality of fins. The module includes a temperature sensing component coupled to the fin separating the first and second battery cells. Filler material is disposed within the housing and between the battery cells and the fins to mechanically restrain the battery cells within the battery module housing. The filler materials conduct thermal energy between the battery cells and the fin. The filler material covers a free end of the fin and the temperature sensing component. The temperature sensing component is coupled to a conductor extending out of the filler material.
