The INM - Leibniz Institute for New Materials in Saarbrücken, Germany, is an internationally leading center for materials research, a scientific partner to national and international research institutions, and a provider of research and development for companies throughout the world. The INM is an institute of the Leibniz Association and has about 250 employees.


The INM research department Structure Formation (SF) invites applications for a Postdoctoral Researcher position within the BMFTR-funded research project “RevEl - Reversible Electrodes for Resource-Efficient and Circular Energy Storage".


Project Description:


The RevEl project aims to replace PTFE-based dry binders with fluorine-free nanocomposites that combine mechanical robustness during battery operation with controlled debonding-on-demand at end-of-life to enable direct recycling.


Within this project, the focus of Structure Formation Department (SF) is on developing and characterizing the hybrid binder systems. The research integrates polymer science, composite engineering, interfacial mechanics, and chemical polymer design to eastablish a new binder type that is suitable for industrially scalable dry electrode processing.


The successful candidate will play a central role in engineering fibrillar composite architectures that mimic PTFE performance while introducing recyclability and regulatory compliance.
