The optimization of lithium-ion batteries is the focus of many efforts to improve the performance and cycle stability of battery systems. The automotive industry in particular places high demands on fast charging capability and power density. Due to physical limits, however, there is a maximum of the effective loading density. Defined flow paths for the electrolytes used are required to increase the loading density. A new technique to create these flow paths is the structuring of highly charged electrodes by means of laser radiation. Here, besides the technical implementation, economic issues are also of great interest, since an additional process step is introduced compared to the standard production of unstructured electrodes.
Within the scope of the bachelor/student thesis, experiments to determine achievable cycle times as well as scaling investigations are to be carried out on the relevant laser systems. On the basis of the determined process parameters, a profitability analysis of possible process times and investment costs is to be carried out.
