Rechargeable lithium-ion batteries used in everyday gadgets, electric vehicles, and to store renewable energy could be a growing source of the “forever chemicals” that pollute soil and waterways, new research suggests.
“Forever chemicals” encompass thousands of different kinds of per- and polyfluoroalkyl substances (PFAS). For decades, they’ve been used to make products more resistant to water, stains, and heat. More recently, a particular subclass of PFAS called bis-perfluoroalkyl sulfonimides (bis-FASIs) has been used as electrolytes and binders in lithium-ion batteries.
Those bis-FASIs are now showing up in soil, sediment, water, and snow surrounding manufacturing facilities, according to research published yesterday in the journal Nature Communications. The study authors also found bis-FASIs in liquids that leached from landfills.
. . . Taken together, it points to lithium-ion batteries as a potential vector for forever chemical pollution from cradle to grave. Without taking action, it’s a problem that could grow as more pieces of our lives become all-electric — from cars to homes and buildings.
Tesla battery life is more around 20-30 years based on current estimates of 250k-500k mile life. The current degradation for a 10 year old model S is 90% of original range. Seeing that the only scheduled maintenance is tires, 12v battery and break pads (estimated to go 100k miles due to regenerative braking) it’s not all that bad.
