Preview: LSE’21 – Virtual Laser Symposium Technology Trends for Electromobility

The more electromobility gets going, the more in demand are technologies that promote the economic production and contact of efficient energy storage systems. Experts from industry and research will present new paths and trends in laser technology at the third Laser Symposium Electromobility – LSE’21 on 19 and 20 January 2021. The two-day online event of the Fraunhofer Institute for Laser Technology ILT will focus on highly efficient laser processes for battery technology.

After the second symposium on electromobility in Aachen, which was fully booked with 70 participants, the third edition of the LSE will start at the end of January 2021 as an online event for interested parties from industry and academia. “In a proven form, the application possibilities of laser technology for the production of battery modules and packs in the e-mobility sector are in the foreground,” explains André Häusler, team leader for the microjoining of metallic materials at Fraunhofer ILT. Laser-based joining processes can be used to create a wide range of high-precision and secure connections that will inspire future battery and contacting technology.

Focus on industrial use and basics of laser processes

Laser tools have long been indispensable in industry. Dr Jan-Philipp Weberpals from Audi will present “Flexible Use of Laser Beam Technology for E-Mobility” in modern e-mobility production by large manufacturers at the first event day at 3:45 pm.

In addition to application possibilities, the focus is also on the basics of laser processes, whose understanding of the industrially used processes is of great importance. A highlight is the lecture “A View into the Invisible – Synchrotron Radiation Allowing Insights into Microscopic Laser Processes” by Marc Hummel, research assistant at Fraunhofer ILT (January 19, 10:45 am). He presents the research results of the team of scientists from Aachen and Stuttgart, which in October 2020 investigated laser welding processes of metals using synchrotron radiation at the German Electron Synchrotron DESY in Hamburg. The different phase boundaries can be made visible in the process, so that the melting bath, the welding depth and the pore formation can be evaluated with high temporal and spatial resolution.

The topics of laser bonding, laser welding and thin film processes for battery production and contactase as well as solutions and perspectives for process monitoring in production will be discussed in further lectures at LSE 21. Speakers include Benjamin Mehlmann (F&K Delvotec Bondtechnik), Dr Reiner Ramsayer (Bosch), Dr Christian Otten (LaVa-X), Dr Markus Kogel-Hollacher (Precitec), Prof Achim Kampker (RWTH Aachen University) and Johanna Helm and Dr Christian Vedder (both Fraunhofer ILT).

Close to the laser processes with virtual laboratory guides

The Aachen-based scientists are also presenting new developments for laser-based welding applications via live transmission from several laboratories of Fraunhofer ILT and the Chair of Production Engineering of E-Mobility Components (PEM) at RWTH Aachen University. Häusler explains: “In the virtual laboratory tours, among other things, interested parties have the opportunity to observe various laser joining processes and to ask questions about them directly via chat or call to the experts.” (Source: Fh.
