Transport device with low-tension foil guiding for the production of batteries

Abstract

Proposed is a transport device for transporting a carrier in the form of a foil for producing electrodes for energy accumulators, in particular electrodes for lithium-ion batteries, having at least two rollers on which the carrier is able to be borne, and of which at least one of the rollers is provided with a drive so as to, by rotation of the driven roller, move the carrier along the longitudinal extent thereof, and transport the carrier from roller to roller. Provided for improving the manufacturing quality is a drive device for generating an additional force which facilitates transport and which for generating an alternating magnetic field has an alternating field generator that generates a temporally changing magnetic field so as to induce eddy currents in the carrier, and so as to exert a Lorentz force on the charges flowing in the carrier as a consequence of the eddy currents.
