Abstract: A battery module includes a housing including a first interior surface, a second interior surface opposite the first interior surface, and a compressed cell assembly disposed within an interior space of the housing between the first and second interior surfaces. The compressed cell assembly includes a plurality of prismatic battery cells arranged in a cell stack that includes a first end, a second end opposite the first end, and a retaining wall disposed between the first end of the cell stack and the first interior surface of the housing. The retaining wall includes a first surface in contact with the first end of the cell stack and a second surface opposite the first surface that contacts the first interior surface of the housing. The first and second interior surfaces are configured to maintain the compressed cell assembly in a compressed state having a compression force above a predetermined threshold.

Abstract: An electrochemical cell includes a cell element and a current collector disposed in a housing that includes a vent. The current collector includes an outer member and an inner member coupled together by one or more flexible arms. The outer member is coupled to the cell element and the inner member is coupled to the vent, such that the flexible arms allow axial movement of the inner member with respect to the outer member when the vent moves from an undeployed position to a deployed position. The housing may include a shoulder that holds the cell element in the housing. The electrochemical cell may also include a coil plate provided at an end of the cell element. The coil plate is coupled to an edge of at least one electrode of the cell element. The outer member of the current collector may be coupled to the coil plate and the inner member of the current collector may be coupled to the vent, such that when the vent moves from an undeployed position to a deployed position, the cell element remains substantially fixed within the housing.
