In the department of Computational Electrochemistry, mathematical models of the chemical and physical processes in batteries are developed for an in-depth analysis by means of numerical simulations. The aim is to gain detailed insights into the complex multiscale processes that allow optimization of the battery design with respect to performance and aging.
What to expect
This master thesis focuses on next-gen lithium-sulfur cells with sulfurized polyacrylonitrile (SPAN) as a novel cathode material. Although these cells have been shown experimentally to have a high potential for aerospace applications, the interaction of chemistry and transport is poorly understood at the model level. However, the latter is essential for an optimal performance.
Therefore, this master thesis aims to develop optimal transport models using data-driven methods. The inverse modeling is realized using the Python solver Firedrake, whereby rate tests and impedance measurements of the cells from experimental project partners are available as a data basis.
Your tasks
Following topics should be addressed:
- literature study on data-driven development of transport models
- selection, implementation and evaluation of suitable approaches
- development of a methodical workflow that appropriately takes into account the physical information content of different data bases
- sensitivity analysis with regard to the quality of the input data
- validation of the optimal set of transport equations
- documentation of the work
The work offers the opportunity to make an important contribution to the further development of lithium-sulfur batteries as a future technology by utilizing synergies between classic methods and modern data-driven approaches.
Your profile
- modelling of transport processes
- data-driven methods
- python programming
We look forward to getting to know you!
