The new battery technology SALD should enable electric cars to have a range of more than 1000 kilometers. With a coating as thin as an atom. EVs in Vancouver could be one of the first to sell EVs with SALD technology.
Will this be the breakthrough in battery technology for electric cars?
A new super battery could enable ranges of more than 1000 kilometers in around two years – even 2000 kilometers should be possible. The new technology that is supposed to ensure this quantum leap is called “Spatial Atom Layer Deposition” (SALD) and was developed in a joint project of the German Fraunhofer Institutes and the state research institute The Netherlands Organization (TNO) in the Netherlands.
A company for the marketing of industrial mass production called SALD BV has already been founded. According to the Eindhoven-based company, “countless inquiries” have already been received from investors about participation.
SALD batteries should offer not only three times the range but also five times the charging speed in a space similar to that of current e-car batteries, as SALD BV announced. This could charge an electric car to about 80 percent in ten minutes and fully in 20 minutes. “It’s not about setting a theoretical range record. We’re talking about the fact that, even in the worst-case scenario, the battery in an e-car with a sporty, dynamic driving style and air conditioning or heating still has at least 20 to 30 percent charge left after 1000 kilometers,” said SALD CEO Frank Verhage. The new battery generation should be ready for use in 2022 or 2023, and talks have already been held with car manufacturers. The technology also harmonizes with the new lithium iron phosphate battery from Tesla for the Model 3 in China.

Electric car battery technology with atomic coating
Basically, the new batteries are a further development of the lithium-ion batteries commonly used in electric cars. What is special about the SALD technology is an industrial process for ultra-thin coating in 3D format – the so-called atom coating – which is intended to significantly improve the ion flow between the anode and cathode. The three-dimensional coating should work both with the liquid electrolytes currently in use and with solid-state batteries, which are considered to be the next big step in battery technology for electric cars. The safety and longevity of batteries should also be improved with SALD .
