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.
Claims13
A method for cutting electrode foils that are intended for use in a battery cell, wherein the method is carried out with a cutting device that comprises a cutting tool, a vibration device, and a particle feed line, and comprises the following steps:
- a) providing an electrode foil with a surface;
- b) arranging the cutting tool over the electrode foil with a separation from the surface;
- c) introducing particles from the particle feed line into the cutting device;
- d) exciting the cutting tool to vibration by means of the vibration device;
- and
- e) applying the vibrations of the cutting tool to the electrode foil via at least one particle that is interposed between the cutting tool and the electrode foil, whereby the electrode foil is cut.
A device for cutting electrode foils that are intended for use in a battery cell, comprising:
- a cutting tool, wherein the cutting tool is positioned above the electrode foil with a separation from a surface of the electrode foil,
- a particle feed line for supplying particles to the cutting tool or to the surface of the electrode foil positioned opposite of the cutting tool, and
- a vibration device for exciting the cutting tool to vibration,
- wherein the device is configured to cut the electrode foil as a result of the vibrations of the cutting tool that are transmitted to at least one particle that is interposed between the cutting tool and the electrode foil.
