Researchers develop new methods for lithium battery recycling and sustainability

Scientists are advancing new techniques to mitigate the environmental impact of lithium-ion batteries through recycling and improved manufacturing components.

In Argentina, researchers at the Institute of Chemistry, Physics of Materials, Environment and Energy (INQUIMAE) have developed the ‘Litio Circular’ project. Led by Ricardo Negri and Ignacio Argento, the initiative aims to recover lithium and other high-demand metals from spent batteries using biomass-derived materials. This process converts hazardous electronic waste into nutrients for agricultural use, addressing both environmental contamination and resource loss. For this innovation, Negri received the 2026 Franco-Argentine Innovation Award.

Separately, engineers from the University of California, San Diego, in collaboration with the Toyota Research Institute of North America, have developed a fluorine-free binder for lithium-ion batteries. Published in Nature Communications, this water-soluble adhesive maintains battery performance while reducing the need for toxic solvents and high-energy drying processes. The new material facilitates easier recycling by allowing components to be separated more efficiently than conventional fluorinated binders.
