Laser applications in battery production — From cutting foils to welding the case

E-Mobility has generated a lot of interest in recent times. A big challenge to bring this trend into real life lies in the battery technology. Lithium-ion batteries seem most promising. The production process of lithium-ion batteries is already well known from the mobile phone industry. For E-Mobility battery manufacturers now have to adapt the manufacturing process to their specific needs and to an even higher output. Laser technology is a key element. Besides laser marking, laser cutting and welding is indispensable for the battery cell manufacturing and packaging of these. Remote cutting and welding with high-brightness disk and pulsed lasers allow highest productivity.
