摘要

In Lithium-Ion battery production many different active material coatings are used to serve the individual needs of the final product. Furthermore laser processing becomes the method of choice in the production to allow a maximum degree of freedom and reduce tooling costs. The used electrode coatings and its different components highly influence the laser process and its results in terms of quality and efficiency. To achieve a better understanding of the ablation mechanism high speed video recording was used to allow a more detailed observation of the cutting and ablation mechanism, respectively. Based on these insights an analytical model was created and verified by time resolved shadowgraph imaging and experimental determined laser ablation thresholds.
