Technology and process
One of LaserTec's core competencies is the welding of lithium-ion cells for battery systems. LaserTec has developed a laser welding technology for temperature-sensitive cylindrical and prismatic lithium-ion battery cells. Since 2015, we have been providing laser welding services for assembling cells into battery modules for electric vehicles. We weld the cells in a charged state, so safety is paramount.
Our experience and laser technologies are used in the joining of lithium-ion cells and battery housings as well as in the laser welding of fuses. LaserTec can also develop a solution for any other issue in the field of laser technology for the battery industry.
Laser welding technology precisely delivers energy to batteries. Laser welding creates secure electrical connections between battery cells.
Laser welding is a good choice for joining cells to connectors in battery assembly. It produces high-strength welds for all material combinations. The process is easily adapted to a wide range of connector designs. Laser welds in aluminum, copper or nickel have higher shear and peel strength than connections made with other technologies.
Due to the high level of automation and the speed of laser welding, the overall process time is significantly reduced, enabling a repeatable connection of cells and an increased production capacity.
