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: MER00040T5 In Group Research & Development (RD), we design the automotive generations of the future. We mean innovative products with the highest quality and efficient development processes. We are already working on vehicles that will secure the technology leadership of Mercedes-Benz in the future. Our department is responsible for research on future electric drives in the field of Mercedes-Benz AG. In the team ''Cell Material Analytics' at Untertürkheim, special analysis methods are developed to characterize the chemical/physical effects occurring in battery cells. One focus is on the transport parameters of electrolytes, among other things for parameterizing physical cell models. In the context of this final work, the dependence of central transport properties on the electrolyte composition is to be investigated. The focus is on currently relevant electrolyte systems in which both the solvent mix and the salt mix used are varied in a targeted manner. Basic transport parameters such as diffusion coefficient, ionic conductivity, thermodynamic factor and the transference number are investigated. The aim is to develop a deeper understanding of the relationships between electrolyte composition and transport properties. A further focus is on the application, further development and, if necessary, improvement of established experimental methods for determining these parameters. For this purpose, systematic measurement series are carried out on suitable electrochemical cells and the results are evaluated with regard to their significance and reproducibility. The results are intended to contribute to the further development of physically sound cell models and provide new insights into the influence of modern electrolyte formulations on transport behavior. These challenges come to you: Construction and testing of electrochemical cells in laboratory scale

Conducting systematic measurement series with varying electrolyte compositions

Determination and analysis of transport properties (e.g. diffusion, conductivity, transference number, thermodynamic factor)

Application and development of experimental methods

Evaluation and interpretation of electrochemical data

Documentation of measurement results and preparation of evaluation scripts

The activity can begin from July 2026. The final topics will be discussed with the university, you and us.

Immatricated in master's degree in engineering or natural sciences with deepening battery technology

First knowledge of lithium-ion cells or electrolytes for high-voltage batteries is desirable
