Junior Research Group Leader (JRGL) Preparation Program


Early career researchers who work on post-lithium batteries or related topics and who look for a stimulating and excellent environment to pursue their research ideas are invited to apply now for one of two available positions in the POLiS Junior Research Group Application Program (JuRaGAP). The application deadline is May 16 (exclusion date).

PhD Position (m/f/d): Development of filament materials for fused filament fabrication (FFF) 3D printing of all solid-state sodium ion batteries (ASSSIB)

Organizational unit

Institute for Applied Materials - Applied Materials Physics (IAM-AWP)

Job description

The position is a cooperation with the Institute for Applied Materials – Materials Science and Engineering (IAM-WK).

This position is to be filled within the Cluster of Excellence POLiS and the overall goal of the related project is to develop a 3D printing process as manufacturing technology for post-lithium all-solid-state sodium ion batteries (ASSSIBs) and to evaluate, optimize these processes in battery performance. Exploring various techniques to improve battery-manufacturing processes is of great interest for the research community as well as for the industry, and 3D printing fused filament fabrication (FFF) is a very promising approach in the battery production process to introduce additive manufacturing technology.

The goal of the thesis is to gain understanding in printing material development and thermally post processing, to increase the thickness of the electrode layers without worsening the cell performance in production of sodium ion batteries followed by thermal characterization and safety analysis. This includes the complete process chain of preparing and characterizing of the printing materials, up to the electrochemical investigation of the electrochemical cells and the feasibility for upscaling. The know-how of material production as well as of 3D printing is already available in both institutes.

We offer you the opportunity to complete the promotion within three years. During this time, you will work in an interdisciplinary working group at IAM-AWP and IAM-WK. You will have access to the excellent research infrastructure and experimental facilities at KIT. The work will be conducted also in cooperation with the research group of Physical chemistry of solids – solid-state ionics and electrochemistry at Justus-Liebig university of Giessen. You will also be a member of the graduate school electrochemical energy storage (GS-EES).

Starting date


Personal qualification

  • University degree (Diploma / Master) in materials science, process engineering, mechanical engineering, chemistry or similar qualifications
  • Knowledge in the field of electrochemistry, especially in electrochemical impedance spectroscopy (EIS) and of thermal characterization methods is desirable.
  • Practical skills and technical understanding of process steps
  • First battery and 3D printing research experience/internships would be an asset, but are not required.
  • Proficiency in English language (B2/C1) and German language (C1) is obligatory.
  • Excellent ability to cooperate with internal and external project partners.
