Developing and optimizing polymer electrolyte formulations
Designing and fabricating multilayer polymer electrolyte architectures
Evaluating ionic transport and performance by integrating polymer design tasks with electrochemical measurements
Publishing results in scientific journals and presenting findings at international conferences
Actively contributing to a collaborative research environment involving PSI and international partners
Your profile
PhD degree in polymer science, materials science, chemistry, electrochemistry, or a closely related field
Strong background in polymer synthesis, polymer modification, polymer physics, polymer electrolyte development
Experience with polymer processing techniques and understanding of polymer structure–property relationships
Interest in applying polymer science to solid state battery materials
Familiarity with electrochemical testing or materials characterization is an advantage
Strong problem solving skills and the ability to work both independently and within interdisciplinary collaborations
Excellent communication skills in English
We offer
Our institution is based on an interdisciplinary, innovative and dynamic collaboration. You will profit from a systematic training on the job, in addition to personal development possibilities and our pronounced vocational training culture. If you wish to optimally combine work and family life or other personal interests, we are able to support you with our modern employment conditions and the on‑site infrastructure.
