It appears we're getting one step closer to better EV batteries! https://phys.org/news/2019-06-economical-energy-storage-electric-car.html
If the technology is able to work in practice this could be huge for electric vehicles and batteries going forward.Researchers at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new production process with the aim of efficient and environmentally friendly future battery production. They coat the electrodes of the energy storage cells with a dry film instead of liquid chemicals. This simplified process saves energy and eliminates toxic solvents. A Finnish company is currently successfully testing the new IWS technology in practice.
No more toxic solvents—lower electricity costs
It is exactly this fact the Saxon Fraunhofer engineers want to change: "Our dry transfer coating process aims to noticeably reduce the process costs in electrode coating," emphasizes IWS project manager Dr. Benjamin Schumm. "Manufacturers can eliminate toxic and expensive solvents and save energy costs during drying. In addition, our technology also facilitates the use of electrode materials that are difficult or even impossible to process wet-chemically."
But these materials are needed for future batteries with higher energy density. "For all these reasons, we think that our technology can help to achieve internationally competitive battery cell production in Germany and Europe."
