Abstract
A method for cutting electrode foils and a device for cutting electrode foils that are intended for use in a battery cell are proposed. The cutting device comprises a cutting tool, a vibration device for exciting at least the cutting tool to vibration, and a particle feed line for feeding at least particles. The cutting tool can be arranged above the electrode foil with a separation from a surface of the electrode foil, and the electrode foil can be cut at least as a result of the vibrations of the cutting tool that are transmitted to at least one particle.
