1. A method for connecting electrode sheets in a roll-to-roll process, the method comprising:
positioning a flexible connection sheet between a first electrode sheet and a second electrode sheet;
coupling the first electrode sheet to the flexible connection sheet by coupling a first side of the first electrode sheet to a first side of the flexible connection sheet; and
coupling the second electrode sheet to the flexible connection sheet by coupling a first side of the second electrode sheet to a second side of the flexible connection sheet.
