‘Forever chemicals’ used in lithium ion batteries threaten environment, research finds

A subclass of PFAS has been found near manufacturing plants and landfills, and in remote regions of the world

Toxic PFAS “forever chemicals” used in lithium ion batteries essential to the clean energy transition present a dangerous source of chemical pollution that new research finds threatens the environment and human health as the nascent industry scales up.

The multipronged, peer-reviewed study zeroed in on a little-researched and unregulated subclass of PFAS called bis-FASI that are used in lithium ion batteries.
