Everyday Batteries Linked To "Forever Chemicals" Contamination: Study
NDTV
Lithium-ion batteries, used in various electronics and electric vehicles, may be a growing source of "forever chemicals" known as PFAS.
Rechargeable lithium-ion batteries-which are widely used in everyday electronics, electric cars, and the storage of renewable energy-may be an increasing source of "forever chemicals" that contaminate land and waterways, according to a recent study.
"Forever chemicals" are the mass-produced, heat-, stain-, and water-resistant products that have been made for decades using thousands of per- and polyfluoroalkyl substances (PFAS). In lithium-ion batteries, a particular subclass of PFAS known as bis-perfluoroalkyl sulfonimides, or bis-FASIs, has been employed recently as binders and electrolytes.
Research published in the journal Nature Communications found that bis-FASIs are now present in soil, sediment, water, and snow around manufacturing facilities. The study also detected bis-FASIs in liquids leaching from landfills.
