A recent study published in Nature Communications highlights a concerning issue in the field of clean energy infrastructure. Specifically, a novel sub-class of PFAS, called bis-perfluoroalkyl sulfonimides (bis-FASIs), found in lithium-ion batteries is causing pollution in air and water sources.
The research, conducted by a team from Texas Tech University, discovered that these bis-FASIs demonstrate environmental persistence and ecotoxicity similar to older, problematic compounds like perfluorooctanoic acid (PFOA). These findings raise important questions about the manufacturing, disposal, and recycling of clean energy technologies like lithium-ion batteries.
As the demand for lithium-ion batteries continues to rise in applications such as electric cars and electronics, the researchers emphasize the need for innovative technologies, manufacturing controls, and recycling solutions to mitigate the environmental impact of PFAS pollution.
Sampling air, water, snow, soil, and sediment near manufacturing plants in various locations revealed high concentrations of bis-FASIs, suggesting widespread pollution. Toxicity testing showed adverse effects on aquatic organisms, fueling concerns about human health risks and environmental damage.
The study also identified treatment methods, such as granular activated carbon and ion exchange, that can effectively reduce bis-FASI concentrations in water sources. This underscores the importance of proactive measures to address PFAS contamination in the environment.
Overall, the researchers urge for collaboration among scientists, engineers, policymakers, and other stakeholders to promote the adoption of clean energy technologies while minimizing their environmental footprint. By developing sustainable solutions and enhancing existing treatment approaches, the transition to a cleaner energy future can be achieved without exacerbating pollution issues.
