Master Thesis Machine Learning for retired Lithium-Ion Cell Sorting (all genders)
Darmstadt

As electric mobility continues to expand globally, sustainable recycling and second-life utilization of traction batteries are becoming increasingly critical. At Fraunhofer LBF, we are developing an automated disassembly system for electric vehicle batteries. A key component of this process is the rapid and reliable evaluation of individual cell health.

The master thesis focuses on the development of a machine learning model for the automatic sorting of used lithium-ion cells based on custom electrochemical impedance spectroscopy (EIS) data. The objective is to build a model that processes EIS measurements and assigns cells to the appropriate sorting category. The sorted cells are subsequently grouped according to their intended secondary use.

A dataset for training and testing the model will be provided. In addition, the thesis should investigate how different types of EIS data influence sorting accuracy and model performance.
