摘要： A lithium-ion battery cell includes a casing, a first terminal pad having a first polarity and positioned proximate the casing, a second terminal pad having a second polarity opposite to the first polarity and positioned proximate the casing, and a reversal device formed into the casing and responsive to an increase in internal pressure within the casing so as to cause a short circuit between the first terminal pad and the second terminal pad when the internal pressure reaches a threshold. The reversal device has a folded configuration and an unfolded configuration, and is configured to transition from the folded configuration to the unfolded configuration in response to an increase in the internal pressure from below the threshold to the threshold.

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(96) 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 (120) and a vent disk (117) 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： Embodiments of the present disclosure are directed to a breathable vent plug that includes a vent plug portion and a breathable vent portion. The breathable vent portion according to various embodiments may be disposed within the vent plug portion to enable relatively low flow rates of gas to flow into and out of the battery module housing, while maintaining liquid tightness. Further, the vent plug portion may include a seal that is configured to rupture and/or otherwise dislodge both the vent plug portion and the breathable vent portion to enable a quick release of pressure from within the battery module housing.
