Title:
TRANSPORT DEVICE WITH LOW-TENSION FILM GUIDE FOR BATTERY MANUFACTURE
Document Type and Number:
WIPO Patent Application WO/2023/099069
Kind Code:
A3
Abstract:
The invention relates to a transport device (1) for transporting a film-like carrier (2) for producing electrodes for energy storage devices, in particular electrodes for lithium-ion batteries, with at least two rollers, on which the carrier (2) can be supported, and from which at least one of the rollers is provided with a drive in order to move the carrier (2) along its longitudinal extent by rotating the driven roller, and to transport the carrier (2) from roller to roller. In order to improve the production quality, a drive device (5) is provided to generate an additional force (8) supporting the transport, which has an alternating field generator (13, 20) for generating an alternating magnetic field, which generates a magnetic field changing over time, in order to introduce eddy currents (6) in the carrier and to exert a Lorentz force on the charges flowing in the carrier (2) as a result of the eddy currents (6).
