NOVELTY - The method comprises leading (S1) objects to be cut into a laser cutting apparatus, cutting (S2) the objects with the laser cutting apparatus, and performing (S3) processing operations at the cutting edges to reduce micro-short-circuits. The step of performing operations at the cutting edges comprises structuring (S3a) of the cutting edges using a laser structuring apparatus and/or applying (S3b) support materials to the cutting edges. The step of structuring the cutting edges is carried out prior to cutting the objects and/or after cutting the objects.    USE - The method is useful for cutting leaf-like or plate-like objects such as electrodes and/or separators for constructing an electrochemical energy storage batteries or parts of the electrodes or separators, where the batteries are useful in a motor vehicle (claimed).    ADVANTAGE - The method is capable of effectively and quickly cutting the objects thus ensuring effective and economical manufacture of the electrodes and/or separators with high quality.    DETAILED DESCRIPTION - The method comprises leading (S1) objects to be cut into a laser cutting apparatus, cutting (S2) the objects with the laser cutting apparatus, and performing (S3) processing operations at the cutting edges to reduce micro-short-circuits. The step of performing operations at the cutting edges comprises structuring (S3a) of the cutting edges using a laser structuring apparatus and/or applying (S3b) support materials to the cutting edges. The step of structuring the cutting edges is carried out prior to cutting the objects and/or after cutting the objects. The laser cutting apparatus is used as the laser structuring apparatus for patterning the cutting edges. The step of structuring the cutting edges with the laser structuring apparatus and the step of cutting the objects with the laser cutting apparatus are carried out simultaneously. The step of applying the support materials to the cutting edges and the step of cutting the objects are carried out simultaneously. The support material comprises components with increased absorption-coefficient with respect to the wavelengths used by the laser cutting apparatus. The leaf-like or plate-like objects comprise thermoplastic plastic fibers as a carrier material. The step of cutting the objects is performed at a cutting speed of 0.5-4 m/s such that a portion of the thermoplastic plastic fibers is merged at the cut edges. The step of cutting the objects is partially carried out with a pulsed laser, which has a maximum wavelength of 1070 nm, a pulse duration of 30 ns, a frequency of 500 kHz, an overlap of 90%, a beam quality of less than 2 M2, a power of 5 kW and a laser spot size of smaller than 300 pm. The cutting edges of the objects rest via a slot of a slotted support in the step of cutting the objects, where an ytterbium fiber laser is used for cutting the objects. INDEPENDENT CLAIMS are included for:    (1) a system for cutting leaf-like or plate-like objects such as electrodes and/or separators; and    (2) a battery useful in a motor vehicle.
