PhD scholarship in Diffraction-Based Energy-Resolved Neutron Imaging of Li-Ion Batteries under Operation

Updated: about 20 hours ago

Join our team to develop new advanced diffraction-based energy-resolved neutron imaging methods to visualize the microstructure evolution and transport of Li in rechargeable Li-ion batteries in order to understand the relationship between microstructure, performance and lifetime of the cell. You will be involved in high profile research at the forefront of materials science in collaboration with international large scale research facilities.

We have an available PhD position in the Department of Energy Conversion and Storage (DTU Energy), Technical University of Denmark (DTU). The PhD project will be conducted as a collaboration between the Section for Imaging and Structural Analysis, European Spallation Source (ESS Data Management & Software Center) and the Danish Technological Institute.

The PhD position is part of a new Center of Excellence within hard materials in 3D (ESS Lighthouse SOLID ) with the vision to visualize the internal structure of materials, their creation and change during use – in 3D and on all the relevant length and time scales. Hard materials are essential ingredients in the solution for many of society’s most outstanding issues within e.g. energy, production and CO2 storage. They are ubiquitous in nature in the form of e.g. bones, wood, soil and rocks. SOLID is a cross-disciplinary center that seeks to exploit the strong synergy in methods and science across materials science, geoscience, bone research, forensics and archeology. To enable the 3D visualization SOLID is engaged in building instruments at the World’s most powerful neutron and X-ray sources, ESS in Lund and ESRF in Grenoble, and is in charge of two national X-ray infrastructures, DanMAX at MAX IV and DANFIX at DTU. SOLID also serves a Danish competence center for neutron and X-ray imaging in general, with extensive collaboration with industry.

Responsibilities
You will work with the research project together with an international project team. Based on state-of-the-art designs of rechargeable Li-ion batteries, you will be responsible for constructing an updated model system to be used for the diffraction-based energy-resolved neutron imaging. You will be characterizing the structural and electrochemical properties of the battery cell. You will be testing the lifetime and performance under operating conditions. You will apply and help improve the advanced technique of diffraction based energy-resolved neutron imaging at a large-scale international research facility, and in this way be able to analyze the microstructure evolution and link this with the Li-ion transport in order to understand the relationship between microstructure, performance and lifetime of the cell under the charging-discharging cycles. You will collaborate closely with other PhD students working on high-contrast neutron imaging and spin-phase neutron imaging for the visualization of flows and current distributions. In addition, you will be collaborating with researchers at large-scale neutron facilities, primarily Paul Scherrer Institute (Switzerland) and J-PARC (Japan). A total of 6 months external stay at international research facilities is included in the project.

Qualifications
You must have a two-year master's degree (120 ECTS points) or a similar degree with an academic level equivalent to a two-year master's degree.

The following qualifications are required:

  • Strong competences within solid state physics or solid state chemistry.
  • Experience with programming and data analysis by Matlab, python or similar.
  • Experience with experimental setups and lab-work.
  • Preferably experience with diffraction and/or imaging with neutrons and/or X-rays and/or electrons.
  • Personal drive and being self-motivated.
  • Good communication skills in English.
  • Being able to work independently and in a team.

Approval and Enrolment
The scholarship for the PhD degree is subject to academic approval, and the candidate will be enrolled in one of the general degree programmes at DTU. For information about our enrolment requirements and the general planning of the PhD study programme, please see the DTU PhD Guide .

Assessment
