Apparatus and method for manufacturing unit cells

An apparatus for manufacturing unit cells, the apparatus comprising:

• a lower separator reel configured for unwinding a lower separator sheet;
• a first feeding roller configured to move the lower separator sheet in a first direction;
• a first conveyor configured to move a first electrode in a second direction parallel to the first direction;
• a first header configured to convey the first electrode from the first conveyor and place the first electrode on a top surface of the lower separator sheet, the first header configured to linearly translate the first electrode in a third direction perpendicular to both the first direction and the second direction when the first electrode arrives at a final position overlying the lower separator sheet;
• an upper separator reel configured for unwinding an upper separator sheet;
• a second feeding roller configured to move, in the first direction, a first stack in which the lower separator sheet, the first electrode, and the upper separator sheet are stacked in this order;
• a second conveyor configured to move a second electrode in the second direction;
• a second header configured to convey the second electrode from the second conveyor and place the second electrode on a top surface of the upper separator sheet, the second header configured to linearly translate the second electrode in a fourth direction parallel to the third direction and perpendicular to both the first direction and the second direction when the second electrode arrives at a final position overlying the upper separator sheet;
• and
• a cutter configured to cut, at preset intervals, a second stack in which the lower separator sheet, the first electrode, the upper separator sheet, and the second electrode are stacked in this order.
