Scientists have uncovered a new source of hazardous "forever chemical" pollution: the rechargeable lithium-ion batteries found in most electric vehicles.
Some lithium-ion battery technologies use a class of PFAS chemicals, or per-and polyfluoroalkyl substances, that helps make batteries less flammable and conduct electricity.
Scientists tested more than a dozen lithium-ion batteries used in EVs and consumer electronics like laptops, and found bis-FASIs at various concentrations.
They can also leach into the environment from landfills, where the majority of lithium-ion batteries end up.
AdvertisementThe study said only about 5% of lithium-ion batteries are recycled, and by 2040, there could be some 8 million tons of lithium-ion battery waste.
