Environmental Impact of PFAS in Lithium-Ion Batteries

Lithium-ion batteries power the EV industry but pose environmental risks due to PFAS. A new study finds PFAS in these batteries.

Lithium-ion batteries are essential to the EV industry, driving the move towards cleaner transportation. However, recent findings reveal a significant environmental concern: per- and polyfluoroalkyl substances (PFAS) in these batteries. PFAS, known as “forever chemicals,” persist in the environment and pose potential health risks.

PFAS in Lithium-Ion Batteries

A study published in “Nature Communications” identified bis-perfluoroalkyl sulfonimides (bis-FASIs) in lithium-ion batteries. These chemicals improve battery safety and performance but have severe environmental impacts. Scientists found high PFAS levels in air, water, snow, soil, and sediment samples near manufacturing plants in the US, Belgium, and France.

Environmental and Health Risks

PFAS accumulate rapidly and do not break down, linking them to health conditions like liver damage, high cholesterol, and chronic kidney disease. The study underscores EVs’ importance in reducing carbon emissions but stresses the need to address new environmental challenges.

Jennifer Guelfo, an associate professor at Texas Tech University, emphasized a balanced approach: “Slashing [carbon dioxide] emissions with innovations like electric cars is critical, but it shouldn’t come with the side effect of increasing PFAS pollution.”

Global Concern and Regulatory Challenges

PFAS in lithium-ion batteries is a global issue. Recent studies have found low PFAS levels in European and Chinese water supplies. Bis-perfluoroalkyl sulfonimides (bis-FASIs) are difficult to degrade and have significant ecological impacts even at low concentrations.

Lee Ferguson, an associate professor at Duke University, noted the lack of comprehensive research on these chemicals’ prevalence in lithium-ion batteries, making it hard to assess the full scope of the issue.

Sample Collection and Analysis

The study sampled 75 surface water, 5 tap water, 2 groundwater, 1 snow, 15 sediment, and 21 soil samples from 87 locations near manufacturing plants in the US, Belgium, and France between January and October 2022.

Minnesota Field Sampling

In January 2022, samples were collected near the 3M manufacturing facility in Cottage Grove, MN. The bis-FMeSI levels ranged from 2.04 to 440 ng/L in surface water and up to 2300 ng/kg in soil. Follow-up sampling in June 2022 confirmed significant contamination levels.

Kentucky, Belgium, and France Sampling

Similar sampling in Paducah and Louisville, KY; Antwerp, Belgium; and Salindres, France, revealed bis-FMeSI and other PFAS contaminants at various concentrations, indicating widespread dispersion from manufacturing sites.

Mitigating PFAS Pollution

Most lithium-ion batteries end up in landfills, leaching PFAS into the environment. Only about 5% are currently recycled, and by 2040, there could be around 8 million tons of waste.

Scientists, engineers, manufacturers, and policymakers must collaborate to develop battery technologies and recycling solutions that do not exacerbate PFAS pollution. Guelfo stressed the importance of preemptive evaluation: “We need to be carefully evaluating these chemicals that are being used in sustainable energy infrastructure.”

Industry and Regulatory Actions

Companies like 3M, Solvay, and Arkema are involved in bis-FASIs production. In response to concerns, 3M announced it will exit all PFAS manufacturing by 2025, following a $10 billion settlement over PFAS contamination.

The Environmental Protection Agency (EPA) has set strict PFAS limits in drinking water and is encouraging broader strategies to remove these chemicals, despite ongoing legal challenges from chemical makers and water utilities.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
