Industrial Laser Solutions for the Battery Industry The world is moving away from fossil fuel dependency, causing a rapid rise in the demand for lithium-ion batteries. Laser technology is a pillar in this transition, helping the battery industry improve its cost-effectiveness, production cycle times, and battery performance.
Scien-tists at Fraunhofer ILT in Aachen have recently developed two laser-based manufactur-ing technologies that save energy in production while also making it possible to create battery cells with higher power density and a longer service life.
The world is moving away from fossil fuel dependency, causing a rapid rise in the demand for lithium-ion batteries. Laser technology is a pillar in this transition, helping the battery industry improve its cost-effectiveness, production cycle times, and battery performance. As a green technology, lasers also help lower the environmental footprint.
With this in mind, researchers at the Fraunhofer Institute for Laser Technology ILT in Aachen have developed innovative laser-based technologies for producing lithium-ion batteries — which, in comparison with those produced conventionally, can be charged more quickly and have a longer service lifetime.
“The short interaction time of the laser pulses is sufficient to ablate the material, but also prevents the holes from melting, which means that the battery does not lose power,” explains Matthias Trenn, team leader for Surface Structuring at Fraunhofer ILT.
“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.

Another important limitation for platform-based high-energy laser weapons relates to the infinite magazine concept. Since the truck, ship or airplane must carry the power source for the laser, and that will limit the power source''s capacity, the lasers can only be used for a limited amount of time before they need to recharge their batteries.
Fraunhofer ILT develops energy-efficient, laser-based manufacturing processes for the production and processing of functional layers in battery and fuel cell production. To introduce competitive energy storage systems into the mass market, industry needs to reduce the production costs for battery cells significantly.
Some of them required laser technology: Micro structuring of the electrode surface with ultra-short pulse lasers, for example, reduces subsequently the charging time of battery cells. Drying of electrodes with VCSEL laser …
