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 pro-duced conventionally, can be charged more quickly and have a longer service 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.
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.
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.
A significant improvement of the discharge rate capability of lithium-ion batteries with laser-structured anodes was observed at temperatures of -10 °C, 0 °C, and 25 °C at discharge rates of up to 8C. Moreover, an enhanced fast-charging capability at charge rates as high as 6C was determined.
Scientists at the Fraunhofer Institute for Laser Technology ILT in Aachen have recently developed two laser-based manufacturing technologies that not only save energy in production, but also make it possible to create battery cells with higher power density and a longer service life.
