Abstract
Official abstract text for this publication.
A method for producing an energy cell, in particular an energy storage cell or battery, having the steps of: arranging a plurality of films of the energy cell at a processing location, and cutting the plurality of films in one operation, wherein the cutting of the films is carried out by a laser beam, and wherein the laser beam is guided in a liquid. Also an apparatus for producing an energy cell.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing an energy cell, the method comprising: arranging a plurality of films of an energy cell one above or on top of another in a stack at a processing location; and cutting the plurality of films in one operation, wherein the cutting of the films is carried out by a laser beam, and wherein the laser beam is guided in a liquid, wherein the energy cell is an energy storage cell or a battery, and the films are battery films, wherein the liquid comprises an electrolyte of the battery. 2. The method according to claim 1 , wherein individual films are kept separate or isolated from one another in the stack by respective separators. 3. The method according to claim 1 , wherein the stack of films has a substantially prismatic shape. 4. The method according to claim 1 , wherein the liquid is directed toward the films in a jet and cools a cut edge of the films during cutting. 5. The method according claim 1 , wherein the laser beam is guided onto the films at a processing location in a liquid jet. 6. The method according to claim 1 , wherein the laser beam is guided into the liquid jet through a nozzle. 7. The method according to claim 1 , further including: drying the films after cutting, wherein the stack is placed in a treatment environment for removing the liquid by heat and/or by low ambient pressure. 8. The method according to claim 1 , wherein the energy cell is a lithium-ion battery, and the films are battery films. 9. The method according to claim 7 , wherein the treatment environment is configured as a chamber or container.
