Patent number: 11658369Abstract: 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.Type: GrantFiled: June 24, 2022Date of Patent: May 23, 2023Assignee: CPS TECHNOLOGY HOLDINGS LLCInventor: Xugang Zhang
