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.
Laser 3D manufacturing techniques offer excellent 3D microstructure controllability, good design flexibility, process simplicity, and high energy and cost efficiencies, which are beneficial for rechargeable battery cell manufacturing.
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.
Laser structuring of composite electrodes is one of the most promising approaches regarding battery performance improvement by the 3D battery concept and an increase of battery safety and production reliability.
For laser cutting of electrodes a high degree of process readiness level is achieved, and commercial ns-laser cutter systems adapted to battery manufacturing are available and can be introduced in cell manufacturing. Nevertheless, laser cutting will be further developed regarding next generation of batteries using the thick-film concept.
Besides PLD, the laser ablation method has been used for cutting conventionally fabricated electrode sheets into a desired size or shape [ 109, 110, 111, 112 ]. In the battery cell manufacturing process, the fabricated electrodes are mechanically cut to size using a die cutter and stacked with other cell components.
