ABSTRACT:
A storage battery of the type used in an automotive vehicle has a housing forming a plurality of transversely elongated and upright cells and respective plus sets and minus sets of U-section electrode elements interleaved with each other in each cell. Each such element is unitarily formed with an imperforate sheet-metal back having a pair of opposite edges, respective expanded sheet-metal arms extending from the edges generally perpendicular to the back, and an imperforate connection tab projecting upward from the back. Each back has a horizontal width that is a fraction of the horizontal width of the respective arms. Respective plus and minus bus bars in each of the compartments are connected to the tabs of the respective electrode sets. The arms are multiply expanded, that is each one has a width that is a multiple of its width before it was slitted and expanded. The arm width is equal to at least four times the back width, normally about five times the back width. Typically the back width is between 3 mm and 10 mm and the back has a thickness of between 0.4 mm and 2.0 mm.
