Scientists have identified lithium-ion batteries, commonly used in electric vehicles, as a new source of hazardous “forever chemical” pollution, specifically PFAS or per-and polyfluoroalkyl substances. These chemicals help make batteries less flammable and conduct electricity. High levels of PFAS were found in environmental samples near chemical plants in the US, Belgium, and France.
PFAS, known for their persistence in the environment, have been linked to serious health issues like liver damage and chronic kidney disease.
The research focused on a specific class of PFAS called bis-perfluoroalkyl sulfonimides, found in EV batteries and consumer electronics. These chemicals are difficult to degrade and affect aquatic life even at low concentrations. The study suggests that only 5% of lithium-ion batteries are recycled, with the rest contributing to environmental contamination.
