Solid-State Batteries Reduce Carbon Emissions by 24% to 39%

An cheap, zero-emission mobility system with no negative impact on our health, the climate, and the environment is the goal of the European-based NGO Transport andamp; Environment . It was instrumental in exposing the Volkswagen diesel cheating crisis and pushing for stricter pollution regulations for automobiles and trucks sold in the EU ever since it was created 30 years ago. It has accused numerous European automakers of selling plug-in hybrid vehicles that might have up to 12 times the carbon emissions claimed to the buying public and warned EU regulators of the fraud.

This month, it hired Minviro , a business that specializes in raw material life cycle analysis, to assess the carbon emissions of existing battery chemistries and upcoming solid-state battery technology. Solid-state batteries require less raw materials to produce on average approximately 24 percent less because they have a better energy density. It should come as no surprise that using 24 percent less materials results in 24 percent fewer emissions. Not surprising at all.

EMISSIONS FROM SOLID-STATE BATTERIES Solid-state technology makes batteries lighter, cheaper, and faster to charge by using solid ceramic material to conduct electricity instead of liquid electrolytes. In the second part of this decade, solid-state batteries are anticipated to be employed in EVs, according to battery manufacturers.

Electric vehicles are already far better for the environment than burning oil, and the carbon footprint of batteries is decreasing every year, according to Cecilia Mattea, clean vehicles officer at Tandamp;E. However, solid-state technology represents a significant advancement because it requires significantly fewer components and produces significantly less emissions due to its increased energy density.

THERE MAY BE ADDITIONAL REDUCTIONS According to the study, if solid-state batteries are produced from the most sustainably sourced components, new battery technologies can lower the climatic impact of batteries by an additional 39% when compared to present lithium batteries. In comparison to more widely utilized sources, such as lithium from hard rock extracted in Australia and processed in China, new mining techniques, such as extracting lithium from geothermal wells, offer much lower climate impacts.

Cleaning up the way we collect and process the raw ingredients in solid-state batteries will further reduce their climate impact, Cecilia Mattea continued. The key will be to enhance the supply chain’s procedures. With the help of the EU Battery Regulation, we can make sure that every battery manufactured or sold in Europe is sourced more carefully, has a smaller carbon footprint, and is recycled at the end of its useful life.

Compared to modern lithium-ion batteries, solid-state batteries may require up to 35% more lithium, but far less graphite and cobalt. Government representatives from the EU and members of the European Commission are now drafting the revised Battery Regulation’s final language. Tandamp;E is requesting that MPs make sure the legislation improves lithium recycling targets to 70% in 2025 and 90% in 2030 and encourages the creation of batteries with a smaller carbon footprint. Both are higher than the recommendations made by the EU Commission.

THE LESSON Transportation and the environment are not well-liked by everyone. They are always scurrying around and inserting their probes into tailpipes to check that the exhaust is indeed what the manufacturers claim it to be. However, their research is well documented, so governments must take it seriously even if it is uncomfortable or unpleasant to do so.

Many people can be heard ranting about how electric cars are not as clean as they are made out to be. Organizations like Tandamp;E offer the data and analysis to refute those unfounded assumptions.
