What is described is: a method for cutting leaf-like or plate-like objects, in particular electrodes and/or separators for constructing an electrochemical energy store or parts of such electrodes or separators, wherein the cutting method has the following steps: (S1) leading the objects to be cut (1) up to a laser cutting apparatus (2), (S2) cutting the objects (1) with the laser cutting apparatus (2), and (S3) performing processing operations at the cutting edges (3) in order to reduce micro-short-circuits. The step (S3) of performing operations at the cutting edges (3) for reducing micro-short-circuits can comprise (S3a) structuring of the cutting edges (3) and/or application of support materials to the cutting edges (3). Also described is: a system (10) for cutting leaf-like or plate-like objects (1), in particular for cutting electrodes and/or separators for constructing an electrochemical energy store or parts of such electrodes or separators, wherein the cutting system (10) has a transport apparatus (5), which is designed to lead the objects (1) to be cut up to a laser cutting apparatus (2), a laser cutting apparatus (2) which is designed to cut the objects (1), and a processing apparatus (4, 5) which is designed to perform processing operations at the cutting edges (3) so as to reduce micro-short-circuits. |
