Battery parts, such as battery terminals, and associated systems and methods for making the same are disclosed herein. In one embodiment, a battery part has a base portion that includes one or more undercut sealing portions, each having a root and a lip. The lip can flare outwardly from the root to define an undercut between the root and the lip of the sealing portion. In some embodiments, the battery terminal can include adjacent sealing portions having opposing undercuts defined by overlapping lips of the adjacent sealing portions. Another embodiment includes a forming assembly for use with, for example, a battery part having a bifurcated acid ring with spaced apart lips. The forming assembly can include movable forming members that can be driven together to peen, crimp, flare or otherwise form the lips on the bifurcated acid ring.

A battery unit (1) comprising a plurality of electrochemical cells (2), which each have an electrode arrangement (3) comprising a cathode contact-making element (4) and an anode contact-making element (5), and an accommodating device (6) comprising a plurality of accommodating units (7), which are each separated from one another by side walls (8), wherein in each case the electrode arrangement (3) of an electrochemical cell (2) of the battery unit (1) is introduced into the accommodating units (7), and the accommodating units (7) are closed by at least one electrolytic barrier (10), which is connected to the accommodating device (6), in such a way that the closed accommodating units (7) with the electrode arrangements (3) arranged therein form the electrochemical cells (2) of the battery unit (1).

An electrochemical storage cell is disclosed that comprises a core and a rectangular shell that receives the core snugly therein. The rectangular shell has first and second open ends. A first end cap is used to close the first open end. An anode terminal extends through the first end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A first gasket is secured within the rectangular shell between the first end cap and the core to resiliently hold the core away from the first end cap. A second end cap is used to close the second open end. A cathode terminal extends through the second end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A second gasket is secured within the rectangular shell between the second end cap and the core to resiliently hold the core away from the second end cap.

Disclosed is a non-lead conductive cap for a battery terminal and battery. The battery may comprise a battery housing and a positive and negative terminal, the positive and negative terminal being accessible through the battery housing; wherein the positive and negative terminal further comprise an electrically conductive cap mounted on both the positive and negative terminal, wherein the electrically conductive cap does not comprise lead.

A battery module includes a plurality of battery cells, and a bus bar for electrically connecting the plurality of battery cells, wherein the bus bar includes a bus bar body and a safety unit inserted into a part of the bus bar body and surrounded by the bus bar body, and wherein the safety unit includes a volumetric expansion resin, a conductive material and an adhesive.
