Fraunhofer ILT to host laser symposium on e-mobility in 2020

The symposium will present 16 talks on, for example, laser processes in battery production, laser sources in e-mobility, and production systems in laser material processing.

2020 will be a defining year for electromobility (e-mobility) in the global vehicle industry, as it is when the EU’s binding fleet-wide CO2 emission targets come into effect. Therefore, the Second Laser Symposium on Electromobility (LSE ’20) that will take place at the Fraunhofer Institute for Laser Technology (Fraunhofer ILT; Aachen, Germany) on February 12-13, 2020, becomes a ‘must-attend’ event. The symposium will also offer a laboratory tour at Fraunhofer ILT on February 12th.

After an exclusive look at current research projects, there will be 16 talks on, for example, laser processes in battery production, laser sources in e-mobility, and production systems in laser material processing. The talks will also shed light on process monitoring, laser manufacturing methods, and laser-based treatment and processing of solid-state batteries.

Fraunhofer ILT will present a variety of battery designs and explain how they were engineered for optimum joining. To increase the charging current in the modules, cross-sections of the contacts to be welded must be sized accordingly, leading to a trend toward larger connector sizes. Because there will be some automotive manufacturers attending, there will also be a discussion regarding process monitoring in the production of battery modules.The first Laser Symposium on Electromobility in 2019 was already fully booked; at LSE ’20, Fraunhofer ILT expects to welcome 100 participants from industry and research.The first Laser Symposium on Electromobility in 2019 was already fully booked; at LSE ’20, Fraunhofer ILT expects to welcome 100 participants from industry and research.Copyright: Fraunhofer ILT, Aachen, Germany

Manufacturers’ plans to start high-volume production of electric vehicles means that battery production needs to be sped up. That’s what the research project "High-throughput methods in manufacturing of lithium-ion batteries" aims towards, with a goal to create an automated, fixed-path production line that reduces cycle times by a factor of 10 by linking the assembly, stacking, and bonding processes. This would bring them to under 100 ms per assembled and stacked electrode, boosting productivity and lowering costs.

Another important topic is the blue diode laser, which has an absorption rate of more than 50% in copper alloys, making it more suitable than infrared lasers for joining electrically and thermally conductive contactsa technology that will pave the way for new applications.
