Abstract: A method for stacking a battery cell includes feeding a separator sheet through a guide assembly to fold the separator sheet, inserting a plurality of first electrodes into the separator sheet at a location where the separator sheet has been folded by the guide assembly, forming respective channels in the folded separator sheet including the plurality of first electrodes, inserting a plurality of second electrodes in the respective channels to form a multilayered body, and pressing the multilayered body to form the stacked battery cell where the plurality of first electrodes and the plurality of second electrodes are stacked in an alternating arrangement.

Abstract: An apparatus for cutting electrode sheets includes a conveyor and a laser device. The conveyor is configured to move an original sheet including an electrode portion and an ear portion extending from an edge of the electrode portion. The laser device is configured to move a laser to cut out a tab connected to the electrode portion from the ear portion of the original sheet. The laser device is also configured to move the laser from one edge of the electrode portion to another edge of the electrode portion to cut and separate a respective electrode sheet including the tab from the original sheet. The laser is configured to cut out the tab from the ear portion and cut and separate the respective electrode sheet including the tab from the original sheet as the conveyor is moving the original sheet.

Abstract: A system including an adapter plate, a conveyor, a separator drum, and first and second electrode drums. The conveyor is configured to move the adapter plate continuously and sequentially in a predetermined path between the separator drum to receive a respective separator sheet, the first electrode drum to receive a respective first electrode sheet, the separator drum to receive a respective separator sheet, and the second electrode drum to receive a respective second electrode sheet until a stacked battery cell includes a desired number of respective separator sheets, respective first electrode sheets, and respective second electrode sheets.
