Jülich Research Centre (FZJ)

Münster, Germany

Work group:

IEK-12 – Helmholtz-Institut Münster Ionenleiter für Energiespeicher



Area of research:

PHD Thesis



Job description:

Batteries move our world and are ubiquitous – they start the engine of our cars, they move the hands of your clocks and allow us to take pictures with our cell phones. The Helmholtz Institute Münster for Ionics in Energy Storage as part of the institute of Energy and Climate research focusses on electrolyte research as a key area for future battery concepts. Major research activities comprise the design, synthesis, characterization and processing of more sophisticated battery electrolytes and chemistries. Our institute operates as a branch office of Forschungszentrum Jülich in close cooperation with the University of Münster and RWTH Aachen University, in this way fostering joint research efforts while promoting this important forward-looking field of electrochemical energy storage.


Your Job:


Join the EU-funded SeNSE project to develop battery with a novel combination of silicon-based anode, NMC-based electrode and advanced electrolyteYour tasks in detail:



  • You take participance in regular project meetings with the involved partners from industry and research

  • You are involved in the synthesis of novel electrolyte components, in particular functional additives and co-solvents for lithium-based battery electrolytes

  • You determine the physicochemical (e.g., water content, viscosity, etc.) and thermal (TGA, DSC) properties of nonaqueous aprotic electrolyte formulations

  • You characterize properties and behavior of nonaqueous aprotic liquid electrolyte formulations in lithium-based cells by means of various electrochemical (EIS, LSV, CV, galvanostatic cycling, dissolution tests, plating-stripping experiments), analytical (MS, GC-MS, ICP-OES) and spectroscopic (NMR, FT IR, Raman, UV-VIS) methods

  • You investigate the interfaces between electrolyte and electrodes and their influence on the overall performance and safety of lithium-based batteries and their chemistry

  • You perform different safety tests at the electrolyte and battery level

Your Profile:

  • University degree (MSc) in chemistry or materials science or a comparable field of study
  • Solid knowledge in organic synthesis
  • Background knowledge and proven interest in the field of electrochemistry
  • Fluent in spoken and written German as well as English
  • Strong cooperation and communication skills
  • Structured and independent way of working

Our Offer:

  • Excellent scientific development opportunities at the Helmholtz Institute Münster as well as cooperation opportunities with our other research locations in Aachen and Jülich
  • Opportunity for a part-time doctorate at the Department of Chemistry of the WWU Münster upon fulfillment of the requirements
  • Chance of participating in (international) conferences and project meetings as part of your work
  • Opportunity to gather industry-relevant knowledge about the complete manufacturing process of batteries as part of their scientific work – from the synthesis to the characterization of the assembled batteries
  • Part-time employment with 19.5 hours per week, initially limited to 3 years
  • Pay in line with 50 % of pay group 13 of the Collective Agreement for the Public Service (TVöD-Bund)

Place of employment: MünsterForschungszentrum Jülich promotes equal opportunities and diversity in its employment relations.We also welcome applications from disabled persons.
