Method for manufacturing dry electrodes on a current collector with the aid of a roller system, roller system, dry electrode, computer program product, and computer-readable medium

A method for manufacturing dry electrodes on a current collector with the aid of a roller system, the roller system comprising at least three rollers, the current collector is arranged between a second roller of the at least three rollers and a third roller of the at least three rollers, the method comprising:

• rotating a first roller of the at least three rollers and the second roller in opposite rotational directions;
• pouring powder into a calender gap formed by the first roller and the second roller, the powder being carried on the second roller as a layer;
• triggering a signal, via a control unit, for setting a laminating gap between the second roller and the third roller, in which the third roller and the second roller are moved towards each other in a direction of the current collector;
• rotating the third roller in an opposite direction of the second roller;
• and
• moving the current collector through the laminating gap, the laminating gap being set such that the layer of the powder carried on the second roller is applied to the current collector for forming the dry electrodes,
• wherein prior to the triggering of the signal to set the laminating gap and prior to the layer of the powder carried on the second roller being applied to the current collector, a defective layer of the powder carried on the second roller is removed, via a removal device, the removal device being arranged downstream from the laminating gap in the rotational direction, and
• wherein, during the removal of the defective layer of the powder carried on the second roller, the laminating gap is larger than when the laminating gap is set such that the layer of the powder carried on the second roller is applied to the current collector, and wherein during the removal of the defective layer of the powder carried on the second roller, the current collector is not moved through the laminating gap.
