Lithium-ion batteries’ secret ingredient found in waters

Lithium-Ionen-Batterien können die Umwelt mit PFAS verschmutzen

=================================================================

A new study published in Nature Communications has found that Lithium-Ion batteries could be contaminating the environment with per- and polyfluoroalkyl substances (PFAS). PFAS are a class of chemicals that are persistent in the environment and can potentially harm humans and wildlife. The study found that Bis-Perfluoroalkylsulfonamide (Bis-FASI), a specific type of PFAS, is being used as an electrolyte and binder in Lithium-Ion batteries and is being released into the environment near production sites.

The study was conducted by researchers at the University of Minnesota, Kentucky, Belgium, and France. They took water, sediment, and soil samples from 87 locations in these countries between January and October 2022. The samples were analyzed for PFAS content, and the highest concentrations were found near a 3M production site in Antwerp, Belgium. The researchers also used large water fleas (Daphnia magna) to assess the impact of PFAS on aquatic life.

The study confirms that there is a risk of PFAS release throughout the lifecycle of Lithium-Ion batteries, with the greatest risk occurring during production. The researchers suggest that the EU’s planned ban on PFAS could have significant implications for the chip industry, as it may not be possible to replace all PFAS substances with non-PFAS alternatives.

Experts warn that a blanket ban on PFAS could threaten the continued existence of the halogenated electrolyte industry. Medtech companies are also calling for transitional periods and urging caution before banning PFAS. However, the EU is set to introduce a ban on PFAS by 2025.

The study highlights the need for careful consideration of the environmental impact of Lithium-Ion batteries and the importance of finding alternative materials that are safe and sustainable. It also underscores the need for effective regulation and monitoring of the use and disposal of PFAS substances to prevent harm to both human health and the environment.

In conclusion, the study provides valuable insights into the potential environmental impact of Lithium-Ion batteries and highlights the importance of addressing the issue of PFAS contamination. It emphasizes the need for caution and careful consideration in the regulation and use of these substances to prevent harm to both human health and the environment.
