Abstract: The present invention describes a method for coating porous separator films of lithium batteries and a coated separator film produced as a result of the respective manufacturing method. Laser ablation is used in the method for detaching particles from the target, and the particle flux vaporised by laser pulses is directed to the base material to be coated, to which the material is attached. The so-called roll-to-roll principle can be used in the method, in which the base material to be coated is directed from one roll to a second roll, and the coating occurs in the area between these rolls. In addition, rotating mirrors and a telecentric lens can be used for aligning the laser pulses as a rectilinear pulse front before guiding onto the target material.

Abstract: The present invention introduces a scanning arrangement and a method suitable for coating processes applying laser ablation. The arrangement is suited to prolonged, industrial processes. The arrangement comprises a target, which has an annular form. The laser beam direction is controlled by a rotating mirror locating along the center axis of the annular target. The scanning line will rotate circularly along the inner target surface when the mirror rotates. The focal point of the laser beams may be arranged to locate on the inner target surface to ensure a constant spot size. A ring-formed, a cylinder-shaped or a cut conical-shaped target may be used. The inner surface of the target may thus be tapered in order to control the release direction of the ablated material towards a substrate to be coated.

Abstract: The present invention presents a method for manufacturing tight and porous coatings from metallic, ceramic and organic materials by utilizing composite targets manufactured of two or several materials, which are disintegrated, and producing in this way material flow towards the object to be coated by utilizing short laser pulses directed to the target material. With the method it is possible to produce material structures in a controlled manner, minimizing the needed energy of the laser pulses and heat generation, and with the method it is also possible to improve productivity by correctly choosing the components for the target material.
