Publication number: 20240136495Abstract: A method for manufacturing a component of an electrochemical energy storage device utilizes lithium such that a coating method based on pulsed laser ablation is utilized in the production of an ion-conducting inorganic material layer on at least one surface of a lithium metal anode. At least one material layer is processed by thermal, mechanical, or thermomechanical treatment or by combination of any of these treatments after pulsed laser deposition. A roll-to-roll method can be used in the deposition, in which the substrate to be coated is directed from one roll to the second roll, and the deposition takes place in the area between the rolls. Moving and/or turning mirrors can be used to direct laser pulses as a beam line array to the surface of the target material.Type: ApplicationFiled: February 22, 2022Publication date: April 25, 2024Applicant: PULSEDEON OYInventors: Ville KEKKONEN, Jari LIIMATAINEN

Publication number: 20230056927Abstract: A method is for manufacturing materials for electrochemical energy storage devices. A deposition method based on laser ablation is utilised in the manufacturing of at least one material layer including lithium. The process is controlled using measurement information that is obtained from the spectrum of the electromagnetic radiation generated by laser ablation. A roll-to-roll method can be used in the deposition, in which the substrate (15, 32, 44, 64, 75, 85) to be coated is directed from one roll (31a) to the second roll (31 b), and the deposition takes place in the area between the rolls (31a-b). In addition, turning and/or moving mirrors (21) can be used to direct laser beam (12, 41, 71a-d, 81a-d) as a beam line array (23) to the surface of the target (13, 42a-b, 72a-d, 82a-d, 82A-D).Type: ApplicationFiled: February 23, 2021Publication date: February 23, 2023Applicant: Pulsedeon OyInventors: Jari LIIMATAINEN, Ville KEKKONEN

Patent number: 10927447Abstract: 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.Type: GrantFiled: December 16, 2015Date of Patent: February 23, 2021Assignee: Pulsedeon OyInventors: Ville Kekkonen, Jarkko Piirto, Jari Liimatainen, Fergus Clarke

Patent number: 10573868Abstract: 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.Type: GrantFiled: September 23, 2015Date of Patent: February 25, 2020Assignee: Pulsedeon OyInventors: Jari Liimatainen, Ville Kekkonen, Aleksey Zolotukhin

Patent number: 10557193Abstract: 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.Type: GrantFiled: December 4, 2015Date of Patent: February 11, 2020Assignee: Pulsedeon OyInventors: Jari Liimatainen, Ville Kekkonen
