Jobbeschreibung

Overview

PhD Position – 3D ion beam tomography of next-generation batteries. The PhD research is part of a consortium project on high-performance batteries with academic and industrial partners.

Future battery technologies are urgently needed to make electric mobility and stationary energy storage more affordable, safer and more efficient. The project focuses on Si-rich anodes and pre-lithiation, and uses ion beam analysis (IBA) to quantify Li with spatial resolution, enabling depth-resolved measurements and 3D reconstructions of element distributions in next-generation batteries.

Your Job

The PhD research is carried out as part of the consortium project on high-performance batteries. Your main responsibilities will include:

• Carrying out independent measurements using the world’s first 3D Li tomography facility on battery samples (the battery beamline at the 3 MeV Tandetron ion accelerator at FZJ)
• Optimising the measurement process to achieve the highest possible sensitivity, resolution and reproducibility
• Measuring various materials and battery components supplied by project partners
• Analyzing results using specially developed, AI-based software that enables 3D reconstructions of element distribution
• Complementary analysis using other advanced techniques such as SIMS, Raman, FIB-SEM, µ-CT, etc.
• Compiling results and assessing the influence of process parameters on Li distribution in various next-generation anode concepts

During the PhD, the candidate will gain knowledge of advanced analytical methods for future battery systems and demonstrate their industry-relevant application for process optimisation.

Your Profile
