    Abstract: A battery system includes an electrochemical cell. The electrochemical cell includes a cover having an opening therein. The electrochemical cell also includes an aluminum terminal pad disposed proximate an outer surface of the cover, and having a pad opening aligned with the opening in the cover. The pad opening includes a tapered surface such that the pad opening has a larger cross-sectional width proximate an upper surface of the aluminum terminal pad than proximate a lower surface of the aluminum terminal pad opposite the upper surface and facing the outer surface of the cover. The electrochemical cell also includes a rivet having a body portion extending through the opening in the cover, a head portion disposed in the pad opening of the aluminum terminal pad, and a shoulder extending between the body portion and the head portion. The head portion includes an inverted cone shape corresponding with the tapered surface of the pad opening and having a maximum cross-sectional width greater than a minimum cross-sectional width of the pad opening.

    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.

    Abstract: A battery includes a cell element that is disposed in a housing, and the housing is sealed with a top cover made primarily of plastic. The top cover may include a layer of metallic foil, which may make the top cover more impermeable to moisture. The top cover may also include a vent, which may or may not utilize the metallic foil to determine the primary opening force of the vent. The top cover may also have one or more stiffening ribs that extend downwardly from a bottom portion of the top cover to contact the cell element, so as to limit movement of the cell element within the housing. In addition, the top cover may have one or more conductive terminals that are at least partially overmolded by the plastic of the top cover.
