The basic structure of the laser is illustrated in Figure 1 and consists of the following components: The production of laser light requires a suitable active medium, which can be a gas, liquid, solid, or semiconductor. In this medium, population inversion can be achieved to create the necessary conditions for generating laser light.
The reason being that faster and more precise manufacturing leads to enormous cost savings in production. Modern laser technology using beam deflection units is again proving to be the best solution for efficient production, especially for cutting foil rolls in battery production.
Prepare to uncover the secrets of these extraordinary beams of light! The basic structure of the laser is illustrated in Figure 1 and consists of the following components: The production of laser light requires a suitable active medium, which can be a gas, liquid, solid, or semiconductor.
The research conducted at Fraunhofer ILT demonstrates that laser technology can be used as a digital production process to improve the quality of battery cells and signifi-cantly increase sustainability during manufacturing. “The next step is to scale up the technology from the prototype to an industrial production line,” says Matthias Trenn.
RAYLASE offers a laser beam deflection unit with a wide range of configuration options ideally suited for cutting battery foils -the RAYLASE AXIALSCAN II-50. And more innovative products are in the pipeline.
“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.
