Fluorine-free conducting polymer binders for high-performance lithium-ion batteries

Research question

This project aims to design and develop a new class of fluorine-free conducting polymer binders that combine mechanical robustness, electronic conductivity, and ionic transport, enabling high-performance and long-lasting lithium-ion batteries. Building on recent advances in ground-state electron transfer and ladder-type polymer structures, the research will focus on synthesizing and processing sustainable binders, understanding their structure–property relationships, and integrating them into battery electrodes. Advanced characterization methods will be used to probe their electrical, mechanical, and electrochemical properties, guiding optimization for commercial relevance. 

Sustainability aspects

The project directly addresses the environmental and safety concerns associated with current fluorinated binders such as PVDF. By eliminating fluorine from the binder chemistry and developing water-processable materials, the research will significantly reduce hazardous emissions, improve recyclability, and lower the carbon footprint of battery manufacturing. These advances will contribute to the circular economy, supporting sustainable energy storage technologies aligned with the EU’s Green Deal targets.
