A plurality of cells are disposed in the housing with each of the cells electrically coupled via bus bars integrated into a bus member. Each of the cells includes a plurality of positive and negative electrodes that are spaced by a separator. The negative electrode includes a substrate having tab meeting at a flange that is connected to an active material portion of the electrode. The positive electrode includes a substrate having a tab meeting at a flange that is connected to an active material portion of the electrode.
