摘要： A battery module includes plurality of prismatic battery cells. Each prismatic battery cell includes a casing housing electrochemically active components and a cover assembly. The cover assembly includes a cover, a terminal protruding through the cover, a current collector electrically coupled to the terminal, and an overcharge protection assembly between the terminal and current collector. The overcharge protection assembly includes a spiral disk and a vent disk physically and electrically coupled, wherein the vent disk is between the spiral disk and the terminal and includes a concave structure forming a cavity between the vent disk and the terminal. The vent disk is configured to deform into the cavity and break when a pressure within the casing exceeds a threshold value. The spiral disk is configured to apply a shearing force to the vent disk when the vent disk deforms to facilitate the breakage to interrupt electrical current flow.

摘要： A prismatic lithium ion battery cell includes a packaging having a cover sealed to a can, wherein the cover includes a reversal disk. A conductive member is disposed above the reversal disk and a power assembly is disposed within the packaging. A first terminal pad and a second terminal pad are disposed above the conductive member and respectively coupled to the power assembly. The reversal disk is configured to deflect upwards and to displace the conductive member to contact the first and second terminal pads in response to a pressure within the packaging being greater than a first predefined pressure threshold and thereby form an external short-circuit between the first and second terminal pads via the conductive member. 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.
