Thesis: Characterization and determination of electrode parameters of physicochemical cell models of lithium-ion batteries from April 2025

Life is always about becoming... In life it is about going on a journey to become the best version of our future self. As we discover new things, we face challenges, master them and grow beyond us.

Apply to Mercedes-Benz and find the area where you can develop your talents individually. You will be supported by visionary colleagues who share your pioneering spirit. Joining us means becoming part of a global team whose goal is to build the most desirable cars in the world. Together for excellence.

Number: MER0003GI7 Our work is characterised by the visions and requirements of e-mobility. We mean innovative products with the highest quality and efficient development processes. In Group Research & Mercedes-Benz Cars Development (RD), we design the automotive generations of the future. We are already working on vehicles and components that will secure the technology leadership of Mercedes-Benz in the future. The Center RD/EB is responsible for the entire battery development in the area of the drive development of Mercedes-Benz AG. The Electrochemistry team is responsible for creating and parameterizing electrical and thermal simulation models for the lithium-ion cell. The aim of this thesis is to expand and optimize the existing method for parameterizing electrodes in physical-chemical cell models. For this purpose, both measurement and simulative investigations must be carried out and improved evaluation methods must be developed. The precise orientation of the work ultimately depends on the previous development progress and the personal, professional qualification. These challenges come to you: Introduction to the topic Lithium-ion cells incorporation into characterization methods of electrodes and parameterization of physicochemical cell models Measurement analysis of experimental cells Data processing and evaluation Interpretation of experimental data Simulative validation of parameters Application and development of optimization algorithms to increase parameter accuracy Documentation and presentation of results

The final topics will be discussed with the university, you and us.
