The rising demand for lithium-ion batteries, projected to soar from 700 gigawatt-hours in 2022 to 4.7 terawatt-hours by 2030, highlights a significant environmental concern. Current batteries contain harmful chemicals known as PFAS, or 'forever chemicals,' which are not biodegradable and pose risks to soil and water. Researchers at the University of Chicago are pioneering next-generation batteries that eliminate these harmful substances, aiming to meet consumer demands for performance without compromising environmental safety. This innovation is crucial as battery applications expand across various sectors.
The risk of contamination of soil and water from EV batteries is huge, if improperly disposed at the end of their lifespan.
UChicago researchers said having PFAS in the cathode and the electrolyte is not a fundamental requirement. They claim to have a workaround that doesn’t affect performance.
