Embodiment Construction

[0043] figure 1 and Figure 2a and FIG. 2 s shows a first variant of a device 2 for producing an electrode stack 4 formed from a single cell 5 . Figure 5 One of the single cells is shown. The cell 5 is here formed from an anode 6 and a cathode 8 , wherein a separator 9 is arranged between the anode 6 and the cathode 8 . Furthermore, a further separator 9 is arranged on the side of the cathode 8 facing away from the anode 6 . Here, anode 6 , cathode 8 and separator 9 are joined to one another by lamination. The anode 6 and the cathode 8 are here in the form of plates. Furthermore, the anode 6 and the cathode 8 each have an electrical contact 10 , which is also referred to as a protrusion. For the purpose of improved clarity, the Figure 1 to Figure 3b A single cell 5 is shown simplified in .

[0044] The electrode stack 4 is provided here for a lithium-ion battery (not shown further), for example a (traction) battery of an electrically driven motor vehicle. The device ...

Abstract

The invention relates to a method for producing an electrode stack (4) formed from cells (5) for a lithium ion battery, in particular of an electrically driven motor vehicle, the cells (5) each being formed from an anode (6) and a cathode (8), the cells (5) being fed into receptacles (14) of a rotationally driven or rotationally drivable stack wheel (12), the cells (5) accommodated in the receptacles (14) are conveyed to the stacking box (24) according to the rotation of the stacking wheel (12), the cells (5) are held in the region of the stacking box (24) by means of the stripping arms (22) and transferred from the respective receptacles (14) into the stacking box (24) on the basis of the rotation of the stacking wheel (12), the cells (5) are stacked in the stacking box (24), and the stacked cells (5) are pressed against each other in the stacking box (24). The invention further relates to a device (2) for producing such an electrode stack (4).

Description

technical field [0001] The invention relates to a method and a device for producing an electrode stack formed from a single cell for a lithium-ion battery. Background technique [0002] Such a lithium-ion battery has at least one cell in which an electrode stack is accommodated, which has a number of sheet-shaped cathodes (cathode sheet, cathode film) and sheet-shaped anodes (anode sheet, anode film), wherein , the cathode and the anode are stacked one above the other, for example, and wherein a spacer is respectively arranged between the cathode and the anode. [0003] Electrode stacks with anodes and cathodes stacked one above the other are produced, for example, by means of so-called monolithic stacking. Usually, the individual anodes and cathodes are moved here by means of a gripper system (clamping system). The grippers of this gripper system receive the respective electrode, ie the respective anode or cathode, transport it in a holding manner to the stacking position...
