Abstract
A rolled-electrode battery cell includes multiple, stacked electrode rolls that are stacked along a stacking axis. Each of the electrode rolls has its electrode tabs bonded to an end of the electrodes, so that the electrode tabs extend from the ends of the electrodes along the winding direction of the electrodes. The stacked electrode rolls are bent around respective bending axes that are parallel to their winding axes, and perpendicular to the stacking axis and the winding direction of the electrodes.
