Job description:

Your Job:

In this project, you will be responsible for testing and establishing standardized scalable protocols for the synthesis and characterization of solid electrolytes for solid-state batteries using solid-state synthesis and impedance spectroscopy. These will then be incorporated into solid-state batteries in pouch format with conversion electrodes. The project is researching various synthesis and processing methods to develop universal and scalable protocols. This project is a joint project in close collaboration with the Fraunhofer Forschungsfabrik Münster that requires an efficient and continuous exchange of knowledge and progress with our university and industrial partners.

With our research in the area of Design of Solid Ionic Conductors we aim to expand our research program in the field of scalable processes for the synthesis of solid electrolytes and cathode processing for solid-state batteries in pouch format. Further information about our research can be found here:

Your specific tasks include:

  • Development of reproducible and scalable synthesis, processing and contacting protocols of solid electrolyte samples.
  • Characterization of such samples using methods such as X-ray diffraction, Raman spectroscopy, electron microscopy.
  • Electrochemical characterization of solid electrolyte samples using impedance spectroscopy
  • Processing of the synthesized solid electrolytes and production of composite films for solid-state battery cells in pouch format.
  • Analysis of the measured impedance data for quality control and evaluation of different processing methods.
  • Creation of reports with the analyzed data and preparation of project reports to the funding organization as well as participation and presentation at project-related meetings (both virtual and on-site).

Your Profile:

For this, we are looking for a candidate with profound knowledge in materials chemistry and electrochemical characterization methods:

  • Successfully completed Master`s degree with subsequent doctorate in chemistry, materials science or chemical engineering
  • Previous experience with electrochemical impedance spectroscopy and experience in solid state synthesis is required.
  • Familiarity with various standard measurement techniques (XRD, XPS, Raman, SEM) is an advantage.
  • Knowledge of scalable synthesis and processing techniques for solid-state battery materials is an advantage.
  • Excellent communication skills in written and spoken English are required. German language skills are an advantage but not required.
  • Enjoying collaborating with internal and external project partners.
  • Structured and independent way of working.


Our Offer:

We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:

  • An excellent environment to conduct high quality research at an international level.
  • A lively scientific environment within the Helmholtz Institute Münster of the Forschungszentrum Jülich and opportunities for cooperation with our partners at RWTH Aachen University, Frauenhofer FFB and the University of Münster
  • Comprehensive training programs and individual opportunities for personal and professional development
  • Comprehensive company health management
  • Optimal conditions for balancing work and private life as well as a family-friendly company policy
  • Flexible working hours in a full-time position (39 hours/week) with the option of slightly reduced working hours
  • 30 days annual leave and an attractive solution for bridging days
  • Specific services for international employees, e.g. through our International Advisory Service

We offer you an exciting and varied role in an international and interdisciplinary working environment. The position is limited until 31.12.2026. Salary and social benefits will conform to the provisions of the Collective Agreement for the Public Service (TVöD-Bund), pay group 13, depending on the applicant’s qualifications and the precise nature of the tasks assigned to them.

Place of employment: Münster

In addition to exciting tasks and a collaborative working atmosphere at Jülich, we have a lot more to offer:

We welcome applications from people with diverse backgrounds, e.g. in terms of age, gender, disability, sexual orientation / identity, and social, ethnic and religious origin. A diverse and inclusive working environment with equal opportunities in which everyone can realize their potential is important to us.

This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.


The Helmholtz Association contributes to solving major challenges to assure the future of our society. With more than 39,000 people on staff in 18 national research centres, the Helmholtz Association is Germany’s largest scientific organization. The name Helmholtz stands for concerted research in which networks form the key principle behind inquiring thought and action. Concerted research is efficient and flexible.

The profile of the Helmholtz Association

The Helmholtz Association performs cutting-edge research which contributes substantially to solving the grand challenges of science, society and industry. To succeed in meeting these responsibilities, Helmholtz concentrates its work in six research fields: Energy, Earth and Environment, Health, Key Technologies, Matter, as well as Aeronautics, Space and Transport. Within each of these fields, research programs are developed by our scientists and regularly evaluated by renowned international experts. Their evaluation forms the basis for the programme-oriented funding that is allocated to Helmholtz research. Within the six research fields, Helmholtz scientists cooperate with each other and with external partners – working across disciplinary, organizational and national borders.

Promoting young academics

Helmholtz scientists, a high-performance infrastructure and modern and efficient research management are the ingredients to the Helmholtz Association‘s success and global impact.
Promoting young researchers is a major priority for the Helmholtz Association. Its qualification schemes for young researchers are geared mainly towards PhD students, postdocs and young managers. The Helmholtz Association has set high standards for its talent management. Its strategy begins with targeted recruitment of highly qualified staff at all levels, followed by comprehensive support aimed at further developing their potential. Ensuring equal opportunities is an essential element in all talent management activities undertaken by the Helmholtz Association.

The Helmholtz Graduate Schools and Research Schools at almost all Helmholtz Centres provide doctoral students with the general and specific skills and training they need, as well as ample opportunity to network with other working groups. The period following a doctorate is decisive in determining the direction and success of a scientific career. For this reason, we are about to establish Career Centers for postdoctoral researchers in the Helmholtz centres and a mentoring programme for especially gifted PostDocs in order to foster career orientation. This equips young researchers with the skills they need to go on to head a Helmholtz Young Investigators Group, for example. As a Young Investigator Group leader, junior scientists can independently set up their own group to conduct research in their specialist field.

Within its talent management strategy, the Helmholtz Association pays special attention to the increased recruitment of talented female scientists both from Germany and abroad. To this end, there are currently two funding programs supporting this policy Funding of first-time appointments of excellent women scientists (W2/W3)’ and ‘Funding to recruit top-level international women scientists (W3)’.

The increasing complexity of the content, structures and framework conditions of scientific work today requires researchers to organise their projects, their employees and, of course, themselves in a highly professional and effective way. In response to these demands, we have set up the Helmholtz Management Academy to provide junior leaders in science with professional management training. Furthermore, the Helmholtz network provides a platform for the alumni of the Helmholtz Management Academy and Mentoring programme to come together and share their experiences of leadership, career development and lifelong learning.
