The invention relates to a method for producing an electrode stack made of anodes and cathodes for a lithium-ion battery, in particular of an electrically powered motor vehicle, wherein the anodes or the cathodes are provided with a separator, wherein the anodes and the cathodes are conveyed into receiving areas of a rotationally driven or rotatably driven stacking wheel; wherein the anodes and cathodes received in the receiving areas are conveyed to a stacking compartment by rotation of the stacking wheel; wherein the anodes and the cathodes are held in the region of the stacking compartment by a removal arm and are transferred from the respective receiving areainto the stacking compartment as a result of the rotation of the stacking wheel, wherein said anodes and cathodes are stacked in an alternating manner in the stacking compartment; and wherein the alternately stacked anodes and cathodes are pressed against one another in the stacking compartment. The invention additionally relates to a device for producing such an electrode stack.

The invention relates to a method for producing an electrode stack (4) from monocells (5) for a lithium-ion battery, in particular of an electrically powered motor vehicle, wherein the monocells (5) are each formed from an anode (6) and a cathode (8), wherein the monocells (5) are conveyed into receptacles (14) of a rotationally driven or rotationally drivable stacking wheel (12), wherein the monocells (5) accommodated in the receptacles (14) are conveyed by means of a rotation of the stacking wheel (12) to a stacking compartment (24), wherein the monocells (5) are held by means of a stripper arm (22) in the region of the stacking compartment (24), and are transferred due to the rotation of the stacking wheel (12) from the respective receptacles (14) into the stacking compartment (24), wherein the monocells (5) are stacked in the stacking compartment (24), and wherein the stacked monocells (5) are pressed against each other in the stacking compartment (24). The invention also relates to an apparatus (2) for producing such an electrode stack (4).

A sheet loading device includes a discharge roller pair, a loading tray, a paddle member, a sheet holding member, a tray lifting-lowering drive portion, a top surface detection sensor, and a control portion. The control portion is capable of performing a lifting-lowering operation to arrange the loading tray at a reference position by lowering the loading tray with the sheet holding member arranged at the holding position to turn the top surface detection sensor into an off state, then lifting the loading tray to turn the top surface detection sensor into an on state, and then lowering the loading tray again to turn the top surface detection sensor into the off state and stopping the loading tray. With the loading tray at the reference position, a predetermined clearance is provided between a top surface of a sheet loaded on the loading tray and a rotational orbit of the paddle member.
