Abstract
A method is proposed for manufacturing dry electrodes on a current collector with the aid of a roller system. The roller system includes at least three rollers and the current collector. A first roller and a second roller are rotated in opposite rotational directions. Powder is poured into a calender gap formed by the first rotating roller and the second rotating roller, the powder being carried on the second roller. A signal is triggered with the aid of a control unit for setting a laminating gap between the second roller and the third roller, the third roller and/or the first roller and the second roller moving toward each other in the direction of the current collector. At least the third roller is rotated in the opposite direction of the second roller. The current collector is moved through the laminating gap.
