Postdoc position: Chemist for selective ion scavenging in batteries

Materials science and technology are our passion. With our cutting-edge research, Empa's around 1,100 employees make essential contributions to the well-being of society for a future worth living. Empa is a research institution of the ETH Domain.

Our Laboratory for Advanced Fibers in St. Gallen develops functional polymer fibers with applications in energy storage, health and environmental technologies. We are pioneering a new class of melt-spun liquid-core fibers that selectively scavenge transition metal ions and other degradation products in lithium-ion batteries, mitigating cell damage and prolonging battery life.

Postdoc position: Chemist for selective ion scavenging in batteries

Your tasks

• Develop melt-spun liquid/gel-core fibers with polyolefin sheaths and functionalized, hydrophobic cores
• Explore selective scavenger systems for transition metal (TM) ions and HF, including chelating ligands, reactive nanoparticles and additives
• Optimize melt-spinning, uniaxial stretching, and post-treatment steps to control sheath porosity and ion diffusion
• Acquisition of research grants and writing of scientific publications
• Supervision of students and interns
• Collaborate closely with chemists, materials scientists, and electrochemists.

Your profile

• PhD in chemistry (or a closely related field such as polymer science or materials science)
• Experience with polymer–ion interactions, chelation chemistry, or battery materials is an advantage
• You enjoy interdisciplinary teamwork and are motivated to publish high-impact results
• Fluency in English; German is an asset.
