Abstract
Lithium-ion batteries (LIBs) play a pivotal role in the ongoing trasition toward electrified transportation and renewable energy integration due to their superior energy-storage performance. However, the rapid expansion of the LIBs market has intensified concerns regarding the environmental footprint of battery production, particularly the use of per- and polyfluoroalkyl substances (PFAS).
Conventional electrode fabrication technologies commonly rely on fluorinated binders, such as poly(vinylidene fluoride) (PVDF) and poly(tetrafluoroethylene) (PTFE), due to their excellent electrochemical and mechanical properties. The continued reliance on these fluorinated binders classified as PFAS, has raised concerns regarding environmental sustainability, end-of-life management and emerging PFAS restriction in the European Union. As the development of sustainable battery materials and manufacturing technology becomes increasingly important, the adoption of PFAS-free materials and processes has accelerated significantly.
Herein, we investigate a fluorine-free binder system for high-performance electrodes in LIBs. The developed PFAS-free binder exhibited strong adhesion and mechanical robustness while maintaining stable electrochemical performance, demonstrating its potential as a sustainable alternative to conventional fluorinated binders.
