Method and system for stacking battery cells

A system for stacking a plurality of battery cells, the system comprising:

• a plurality of adapter plates;
• a conveyor configured to move the adapter plates in a predetermined path;
• a separator drum configured to rotate about a first rotational axis to pick up a plurality of separator sheets and release the plurality of separator sheets onto respective adapter plates;
• a first electrode drum configured to rotate about a second rotational axis to pick up a plurality of first electrode sheets and release the plurality of first electrode sheets onto respective adapter plates, the first rotational axis extending non-parallel to the second rotational axis;
• and
• a second electrode drum configured to rotate to pick up a plurality of second electrode sheets and release the plurality of second electrode sheets onto respective adapter plates,
• wherein the conveyor is configured to move each of the adapter plates continuously and sequentially in the 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 each stacked battery cell comprises a desired number of respective separator sheets, respective first electrode sheets, and respective second electrode sheets.

A system for stacking a battery cell, the system comprising:

• an adapter plate;
• and
• a rotary drum configured to rotate about a fixed axis and pick up respective separator sheets and respective electrode sheets from a plurality of feeding devices, the rotary drum defining at least one cutout extending along a circumference of the rotary drum such that the respective separator sheets and the respective electrode sheets extend along a circumference of the rotary drum when the rotary drum picks up the respective separator sheets and the respective electrode sheets,
• wherein the rotary drum is configured to continuously and sequentially release onto the adapter plate:
• a respective separator sheet, a respective first electrode sheet, a respective separator sheet, and a respective second electrode sheet until a stacked battery cell comprises a desired number of respective separator sheets, respective first electrode sheets, and respective second electrode sheets.
