  • More flexible battery design with ultrafast laser ablation

    Press Release / September 08, 2020

    Fast, gentle and reliable:  The Fraunhofer ILT has come up with a process tailor-made to ablate anode material from very thin copper foils at up to 1760 mm³/min. It uses a powerful USP laser to expose surfaces for electrical contacts.

    The ultrashort pulse (USP) laser has been known to shine whenever highly sensitive material needs to be machined quickly yet gently. The Fraunhofer Institute for Laser Technology ILT has investigated one such application that certainly looks to have a bright future: The Aachen-based researchers developed a quick, reliable and nondestructive method of ablating lithium-ion batteries’ anode material with an ultrashort pulsed laser beam. This ablation technique exposes electrical contact points called tabs.

    Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

  • From May 4 to 6, 2022, the AKL – International Laser Technology Congress will once again take place in its usual form.

    Owing to the progressing coronavirus pandemic, the Fraunhofer Institute for Laser Technology ILT has decided to cancel the International Laser Technology Congress AKL in 2020. The safety and health of our attendees, partners and employees has top priority for us. The next AKL will take place from May 4 to 6, 2022, thus maintaining its regular biennial rhythm. However, so that interested parties do not have to wait another two years for the live demonstrations in Europe's largest laser system park, which are firmly anchored in the AKL, Fraunhofer ILT intends to open its doors as early as this autumn and in 2021 for various planned symposia in Aachen – provided that the general conditions allow it again.

    Experts in composites strive to develop and research special combinations of materials for lightweight construction and other innovative applications – results of their work will be on show at JEC World in Paris from March 3 to 5, 2020. As the world’s leading trade fair for the composites industry, JEC World offers comprehensive insights into the entire value chain of custom material manufacturing and processing. The Aachen-based Fraunhofer Institute for Laser Technology ILT will be taking the opportunity to showcase laser-based processes for lightweight materials and hybrid joints.

  • A carbon fiber preform drilled using a USP laser beam with a star-shaped cut-out and a perfectly proportioned metal insert.

    Carbon fiber reinforced polymer (CFRP) components are usually assembled using fasteners. These are typically glued into the CFRP component once it has been cured and drilled. The consortium behind the CarboLase project came up with a new method, using an ultrashort pulsed laser to drill the holes for the fasteners in the textile preform with micrometer-scale accuracy. Integrating the fasteners in these high-precision cut-outs before the CFRP component is cured saves time by shortening the production process. In 2019, the project team’s efforts were rewarded with the prestigious CAMX Award in the “Combined Strength” category.

    Microplastics enter our wastewater and the environment on a daily basis. Yet wastewater treatment plants struggle to filter out enough of these tiny plastic particles. Fortunately, help is on hand in the form of the SimConDrill research project, which the German Federal Ministry of Education and Research (BMBF) has been funding since 2019. Combining the expertise of five partners from industry and research, the aim of the project is to jointly develop a filter featuring tiny, laser-drilled holes that can remove plastic particles as small as 10 micrometers from wastewater. This remarkable innovation has now been nominated for the prestigious Green Award. Until February 14, 2020, you can vote online at https://greentechfestival.com/en/awards/ to support the project.
