A reversibly connected battery pack is provided. The reversibly connected battery pack includes a pair of end frames, at least one frame, a plurality of battery cells, and at least one power connector. One end frame has a positive terminal, and the other has a negative terminal. The frame(s) is positioned between the pair of end frames. Each of the plurality of battery cells has a positive tab and a negative tab. The positive tab of one of the plurality of battery cells is electrically connected to the positive terminal in the end frame, and the negative tab of another one of the plurality of battery cells is electrically connected to the negative terminal in the end frame. The plurality of battery cells are positioned in the frame(s) and the end frames. The plurality of battery cells and the positive and negative tabs are supported by the frame and the pair of end frames. There is at least one power connector electrically connecting the negative tab of one battery cell with the positive tab of an adjacent battery cell.

Integrated stackable battery

A battery cell tab is described. The battery cell tab is anodized on one end and has a metal coating on the other end. Battery cells and methods of making battery cell tabs are also described.

Nickel coated aluminum battery cell tabs

An interconnect member for use in a vibration welded battery module having a battery tab includes a portion weldable to the battery tab, and an inlay. The inlay is positioned with respect to the portion. The inlay may be the same material as the portion, with an insulating or heat-deterring outer ring, or may be the same material as the battery tab with or without the outer ring. Voids or openings may be provided in the interconnect member to reduce the thermal mass of the interconnect member. The voids may be defined by laminated or clad layers of the portion, and may be filled with an insulating material. A battery module is also disclosed having the battery tabs and the interconnect member noted above.
