Doctoral/Postdoctoral Position: Hybrid solid-state electrolytes

The Nanochemistry Department at the Max Planck Institute for Solid State Research (MPI-FKF) in Stuttgart invites applications for a PhD or Postdoctoral Position (m/f/d) for the project “Hybrid solid-state electrolytes” as part of the Cluster of Excellence e-conversion.

Scientific environment

The department is active in the development of new functional materials for solar energy conversion and electrochemical energy storage. Our research operates at the interface between material synthesis and characterization with the goal to understand structure–property–activity relationships in novel energy materials. We employ methods of classical solid-state synthesis, Chimie Douce and techniques of nanofabrication, along with various diffraction, spectroscopic and microscopic techniques to analyze structure (local and long-range), morphology, as well as dynamics and transport of electronic and ionic charge carriers.

About the position

The position offers the opportunity of cutting-edge fundamental research on solid-state battery materials. The project will study the design and function of hybrid solid-state electrolytes in an interdisciplinary project in close collaboration with theory. The focus is on advanced synthesis and electrochemical characterization of inorganic electrolytes and involves bulk synthesis and film deposition, as well as interface and interphase characterization.

Your qualifications

The Nanochemistry Department is looking for a highly motivated doctoral or postdoctoral candidate with a strong background in the synthesis and characterization of inorganic and solid-state materials. The candidate should hold a master’s or doctoral degree in chemistry or related fields. A background in solid-state ionics, battery materials or solid-state electrochemistry would be advantageous. The successful candidate will closely collaborate with theorists and experimentalists within e-conversion and at MPI-FKF and work in a competitive international environment.

The Max Planck Institute for Solid State Research in Stuttgart, Germany, is one of currently 86 institutes and facilities of the Max Planck Society with about 24.000 employees who conducts basic research in the natural sciences, life sciences, and humanities. The international research institute is focused on solid-state materials and how the structures of these materials affect their electrical, mechanical and magnetic properties. Currently about 600 employees are working at the institute. The Max Planck Society strives to ensure a workplace that embraces diversity and provides equal opportunities irrespective of gender, nationality or disabilities of the applicants. Furthermore, the Max Planck Society is committed to increasing the number of individuals with disabilities in its workforce and therefore encourages applications from such qualified individuals.


Master/Ph.D. thesis: Solvent-based synthesis of thiophosphates for lithium ion solid-state batteries

Conventional lithium ion battery technology is close to its physical limit. One way to further improve this technology and increase the safety of the resulting cells is to replace the liquid electrolyte with suitable solid electrolytes. However, these can currently be produced only by energy-intensive and thus expensive high-temperature syntheses.

The Lotsch and Karaghiosoff groups at LMU are looking for interested and committed students for a joint Master thesis and/or PhD project to develop new, scalable synthesis routes for lithium thiophosphate solid electrolytes using solvent routes. To this end, the reactivity of thiophosphate precursors in suitable solvents will be investigated and solvothermal synthesis routes, possibly paired with solid-state chemical synthesis methods, will be explored. The obtained products will be investigated by structural analysis and electrochemical impedance spectroscopy.

What we offer:

  • An interdisciplinary working environment that closely integrates aspects of inorganic molecular chemistry (Karaghiosoff group), solid state chemistry and electrochemistry (Lotsch group)
  • Involvement in the FestBatt competence cluster (BMBF) to help shaping current developments in the field of solid-state battery research.

 What we expect:

  • Interest in fundamental and applied battery research
  • Solid background in inorganic molecular and solid state chemistry
  • Good preparative skills, especially in molecular chemistry (e.g. handling of air sensitive compounds)
  • In-depth knowledge of spectroscopic analytical and diffraction techniques; experience in electrochemistry, especially electrochemical impedance spectroscopy (EIS), is desirable
  • Motivated, structured and independent work style

Would you like to help shape the future of battery science and technology? The Lotsch and Karaghiosoff groups look forward to receiving your application.
