Abstract: A gripper for picking up and gripping individual sheet-like electrodes while manufacturing a battery cell. The gripper has a suction device for aspirating the electrode. The gripper has a first gripper segment and a second gripper segment, wherein the suction device has a first suction device arranged on the first gripper segment for aspirating a first region of the electrode to be gripped and a second suction device arranged on the second gripper segment for aspirating a second region of the electrode to be gripped. The gripper also includes a displacement unit for relatively displacing the first and second gripper segments with at least one directional component parallel to the surface of the electrode to be gripped.

Abstract: Feeding a separator to a Z-folding process at the manufacture of battery cells, in which the separator is fed by: feeding a separator web with a first web tension to a web tension transmission unit which divides the web run of the separator web into sections with different web tensions; guiding the separator web from the web tension transmission unit with a second web tension to a separator guide unit; supplying the separator web in a Z-shape with a reciprocating movement of the separator guide unit in order to stack the battery cell; and controlling the second web tension depending on the position of the separator guide unit. In addition, apparatus, devices, controls, and computer programs for performing the feeding.

Abstract: A cell component de-stacking device for vertically de-stacking separated cell components, including at least one vertical de-stacker with a vertical magazine for accommodating a plurality of the cell components in a vertical arrangement and with a lifting and lowering device for lifting and lowering the cell components in the vertical magazine and for de-stacking separated cell components in the vertical direction, and a delivery device for delivering separated cell components at a filling station to the vertical de-stacker. The vertical de-stacker is configured for filling the vertical magazine at the filling station by individually accommodating the cell components and moving them by means of the lifting and lowering device, and for being moved between the filling station and the stacking station, and for individually dispensing the cell components in the vertical direction at the stacking station by means of a downward movement.

Abstract: Devices and methods to be used in large-scale production of battery cells or fuel cells when forming cell stacks, including a positioning device for positioning the repeating components of the cell stack. The positioning device includes at least one vibrating jaw having a vibrating jaw contact surface, and a positioning jaw which is rigid in operation and is arranged lower than an upper region of the vibrating jaw and has a positioning jaw contact surface. In one embodiment, the jaws engage each other by complementary protrusion-recess features on the contact surfaces. Alternatively or additionally, the vibrating jaw is provided to move along an arcuate path during oscillation, a tangent of the arcuate path lying on the positioning jaw contact surface.
