1. A method, comprising:
rotating a current collector material around a plurality of pallets disposed around an outside edge of a rotating drum, the rotating drum including a plate cam, the plurality of pallets coupled to the plate cam, the plurality of pallets including a first pallet and a second pallet;
drawing a vacuum on the current collector material from within the rotating drum to draw a portion of the current collector material into a gap between the first pallet and the second pallet;
frictionally engaging the portion of the current collector between an edge of the first pallet and an edge of the second pallet;
dispensing a semi-solid electrode material onto the first pallet and the second pallet; and
separating the edge of the first pallet from the edge of the second pallet to form two discrete portions of electrode material.
