In the final phase: laser welding of connecting pieces during battery pack assembly, and laser marking of batteries. The unique advantages of laser processing, such as non-consumable, no burr or dust, flexible automation integration, high production efficiency, and good process stability, make it irreplaceable in lithium battery production.
Electrode layer applied to copper foil and dried with laser technology: Researchers at Fraunhofer ILT have halved the energy required for drying in the production of lithium-ion batteries.
In light of this, researchers at the Fraunhofer Institute for Laser Technology ILT in Aachen have developed innovative laser-based technologies for producing lithium-ion batteries that, compared to those produced conventionally, can be charged more quickly and have a longer lifetime.
“Drying with the diode laser will reduce the energy required by up to 50 percent and the space needed for a drying system on an industrial scale by at least 60 percent,” Fink predicts. In addition to these benefits, the team at Fraunhofer ILT has been able to improve the power density and service lifetime of the lithium-ion batteries.
