Abstract: A traction battery cell assembly including a battery cell and a cell case is provided. The cell case defines a cavity sized for receiving the battery cell and includes an inner wall, an outer wall, and a plurality of support chambers disposed between the inner wall and the outer wall. Each of the support chambers defines a polygon having multiple sides. The sides are arranged with one another to define an agent cavity to house neutralizing agent. The plurality of support chambers is arranged with the inner wall and the outer wall such that an impact to one of the walls causes a puncture to one of the sides of the support chambers releasing the neutralizing agent. Each of the support chambers may include five or more sides and adjacent sides may define an angle therebetween greater than ninety degrees.

Abstract: A pouch battery cell includes a rigid frame forming a skeleton of the cell and defining an aperture, an anode, a separator, a cathode, and a thermal transfer device disposed within the aperture, the anode and cathode each including a current collector with an exposed tab portion bonded to a terminal, integrated into the frame, and the thermal transfer device integrated into the frame and partially extending to the cell exterior.

Abstract: A lithium ion pouch battery cell includes a rigid frame forming a skeleton of the cell and defining an aperture, an anode, a separator, and a cathode disposed within the aperture. The anode and cathode each include a current collector with an exposed tab portion, and a pair of terminals, integrated into the frame, each having an exterior portion and an interior portion bonded to one of the current collectors.

Abstract: A method of making a solid state battery may include heating a flux sandwiched between a solid ceramic electrolyte and a group one metal. The flux may be heated such that it roughens a surface of the solid ceramic electrolyte and the group one metal melts and adheres to the surface of the solid ceramic electrolyte.

Abstract: A plug for a fill port of a battery cell includes a body defining a channel. The plug includes a cover coupled to the body and covering the channel. The cover is configured to open in response to predetermined conditions to vent the battery cell.

Abstract: A battery system is disclosed. The system may include a frame surrounding a battery active region and defining a vent carried by the frame and mounted between the battery active region and coolant passage. The vent may be configured to vent gas from the battery active region to the coolant passage responsive to a pressure or temperature of the gas exceeding a predetermined threshold, and to isolate the battery active region from the coolant passage otherwise.

Abstract: A battery containment structure is provided. The battery containment structure may include a first pliable pouch, a second pliable pouch, and a vent. The first pliable pouch may surround a battery active region. The second pliable pouch may surround the first pliable pouch. The vent may be carried by the first pliable pouch and configured to vent gas from the battery active region responsive to a pressure or temperature of the gas surpassing a predetermined threshold.

Abstract: An exemplary battery support assembly includes a bladder device with a pocket that receives at least one battery cell of a traction battery. The bladder provides a fluid flow path that diverges at an end of the pocket into a first section on a first side of the pocket and a second section on an opposing, second side of the pocket. An exemplary battery support method includes moving a flow of fluid along a fluid flow path toward at least one battery cell; and diverging the flow into a first or second section of the fluid flow path such that the flow moves along opposing sides of the at least one battery cell.

Abstract: A pouch battery cell assembly for a traction battery includes a housing, a first intermediate terminal member, and a first terminal tab. The housing defines a cavity. The first intermediate terminal member is disposed at least partially within the housing and defines an access port open to an exterior of the housing and the cavity which may be sized for electrolyte injection. The first terminal tab is embedded within the first intermediate terminal member. A pressure sensitive release mechanism may be disposed within the access port to selectively vent gases from the cavity. A second intermediate terminal member may be at least partially disposed within the housing and a second terminal tab may be embedded within the second intermediate terminal member.
