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.

The present application relates to a composition, a battery module and a battery pack. According to one example of the present application, it is possible to provide a battery module and a battery pack which have improved heat dissipation properties, adhesive force, adhesion reliability and processability as well as excellent power to volume.

Battery including at least one unit cell formed by an anode, an electrolyte, and a cathode, defining a stack. The stack of the battery has a plurality of faces that includes two end faces opposite one another, two lateral faces opposite one another, and two longitudinal faces opposite one another. The first longitudinal face includes at least one anode connection zone and a second longitudinal face of the battery includes at least one cathode connection zone that is laterally opposite to the at least one anode connection zone.
