METHOD AND DEVICE FOR CUTTING ELECTRODE FOILS

A method for cutting electrode foils () by means of a particle stream () is proposed. A cutting device () for cutting electrode foils () that are intended for use in a battery cell is also specified which comprises at least one nozzle () with an outlet (), one cutting tool (), one vibration device () for exciting at least the cutting tool () to vibration (), one particle feed line () for supplying at least particles (), and one gas feed line () for supplying a first gas stream (), wherein the particles () and the first gas stream () can be mixed in the cutting device () to form a particle stream () and fed via the nozzle () to the outlet (), wherein the cutting tool () and the outlet () can be arranged above the electrode foil () with separation () from a surface () of the electrode foil (), and wherein the electrode foil () can be cut at least as a result of the particle stream () and the vibrations () of the cutting tool ().
