PhD position: Scale-Bridging Numerical Development for dendritic failure in all-solid-state batteries

fAbout us:
The School for Simulation and Data Sciences (SSD), a joint initiative between the Research Center Jülich (FZJ) and RWTH Aachen University, is offering a 1+3-year PhD position in highly innovative computational approaches for the investigation of dendritic failure in all-solid-state batteries. The PhD activity will be integrated into a collaborative research group involving the group of Computational Mathematics at the Center for Computational Engineering Sciences (CCES) at RWTH Aachen University and the chair for High-performance Materials for Efficient Energy Conversion and Storage at the Institute for Energy and Climate Research, IEK, at FZ Jülich. The SSD provides an excellent research environment within the infrastructures of the two participating Institutes, including Europe's most powerful supercomputing centre. The salary is remunerated according to TV-L E13.

The Research Project:
All-solid-state batteries present an attractive alternative to conventional liquid-based battery systems due to their favourable safety properties. However, recent experimental observations suggest the existence of large application-relevant parameter regimes where dendrites can develop, leading to short-circuits and eventually blow-up of the battery. The PhD project aims at developing a novel numerical model for the study of dendrite formation in areas of the electrolyte that are subject to high pressure, e.g., near the electrodes and around material inhomogeneities, where dendrite formation is mainly observed. To this end, two different methodological approaches will be joined into a scale-bridging model, namely a continuum description on the macroscopic scale that is capable of predicting the dynamics of the dendrite formation, and an ab initio model on the microscopic scale to accurately determine the material properties.

Requirements:
We encourage applications from highly motivated candidates with a master degree in Physics, Applied Mathematics, Computational Engineering Sciences or similar. We are seeking for a candidate with a strong interest in simulation and theoretical work in physics. To apply, please send a motivation letter, a CV (including a list of publications, if applicable), two recommendation letters and the transcripts of records of the undergraduate studies (including grades) until July 20th, 2018 to the contacts below. Both RWTH Aachen and FZ Jülich are equal opportunity employers. We therefore strongly encourage applications of qualified women.
