“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.
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 significantly increase sustainability during manufacturing. “The next step is to scale up the technology from the prototype to an industrial production line,” says Matthias Trenn.
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.
Laser structuring can turn electrodes into superwicking. This has a positive impact regarding an increased battery lifetime and a reliable battery production. Finally, laser processes can be up-scaled in order to transfer the 3D battery concept to high-energy and high-power lithium-ion cells.
