cgewin ‘Forever chemicals’ found in electric vehicle batteries
Many are switching to electric vehicles to help save the planetcgewin, fueling the global EV boom.
Ironically, scientists have found “forever chemicals” in their batteries.
Also known as per-and polyfluoroalkyl substances or PFAS, they have devastating effects on the environment and numerous health risks.

How did scientists find forever chemicals in EVs?A new study found that lithium ion batteries—which power millions of electric vehicles—can leach PFAS into the air, water, and soil. https://t.co/4tk7LApZPL
— Fast Company (@FastCompany) July 9, 2024Jennifer Guelfo, an associate professor of environmental engineering at Texas Tech University, and her team know electric cars use lithium-ion batteries.

The researchers say they can travel long distances while airborne, “meaning that areas far from manufacturing sites may be affected as well.”

At the time of writing, there is minimal research regarding bis-FASI health risks. However, Fast Company says exposing fish to these chemicals causes behavioral and metabolism changes.

Worse, forever chemicals take several years to decompose, allowing them to contaminate the environment for a long time.
Lithium-ion battery manufacturing has issues beyond bis-FASIs, such as its massive energy and water consumption. Moreover, mining its raw materials ruins communities and habitats.
“Our results reveal a dilemma associated with manufacturing, disposal, and recycling of clean energy infrastructure,” said Jennifer Guelfo.
“Slashing CO2 emissions with innovations like electric cars is critical, but it shouldn’t come with the side effect of increasing PFAS pollution.”
“We need to facilitate technologies, manufacturing controls, and recycling solutions that can fight the climate crisis without releasing highly recalcitrant pollutants.”
