1. A battery comprising:
positive and negative current collectors; and
a plurality of bipolar electrodes arranged in a stack between the positive and negative current collectors,
wherein the positive and negative current collectors and the stack of the plurality of bipolar electrodes are folded in an S-shape;
wherein first and second electrodes of the bipolar electrodes do not extend into the folds of the S-shaped stack; and
wherein:
the plurality of bipolar electrodes is arranged in the stack along a vertical axis;
the stack comprises rows of the first electrodes and rows of the second electrodes of the bipolar electrodes, the first and second electrodes arranged in respective rows along a horizontal axis, the rows of first electrodes and the rows of second electrodes alternating along the vertical axis forming columns of the first and second electrodes along the vertical axis, each of the columns comprising the first and second electrodes alternating along the vertical axis; and
wherein in each pair of successive columns, the first electrodes in the rows of a first column are separated from the first electrodes in the rows of a second column by distances that increase downwardly in the stack along the vertical axis.
