Abstract: 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.

Abstract: A method is for producing electrochemical energy storage devices utilizing lithium and for producing materials used in the devices, such that the anode has lithium metal, inorganic solid electrolytes. Anode and cathode components are joined together by pressure and/or temperature utilized in the production. The lithium-metal layer is produced at least partly by a pulsed laser deposition method. The method can utilise various inorganic solid electrolytes produced by different methods and a roll-to-roll method as well as different ways to couple pressure and/or temperature to the component being processed.

Abstract: A method is for the manufacture of materials used in electrochemical energy storage devices. The manufacturing utilizes processing of the material layers by pressure and/or temperature, a porous, non-conducting substrate web (1A, 1B, 1C). An organic solid electrolyte (2A, 2B, 2C) is attached to and impregnated into the substrate web. The manufacturing processes a lithium-metal anode (11), and a cathode layer containing cathode-material particles together with polymer solid electrolyte and/or inorganic solid electrolyte and/or liquid electrolyte as well as with other necessary constituents.

Abstract: 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).

Abstract: The present invention introduces a laser ablation arrangement and a corresponding method for PLD applications, where circular scanning patterns are utilized to achieve high scanning velocities on target surfaces for efficient coating process. The arrangement allows for flexible positioning of targets and scan lines in order to optimize coating uniformity on large surface areas as well as high duty cycle for scanning. These features are all essential for achieving efficient industrial coating processes. Fast optical switching and synchronized rotation of scanning mirrors enable efficient distribution of laser energy along long scan line paths on target surfaces.
