Mercedes electric G-Class to use Sila batteries

Mercedes-Benz is adding another cell chemistry to its battery portfolio. This is made possible by a cooperation with Sila Nanotechnologies. The silicon anode chemistry of the Californian company is to be available for the first time as an option for the future electric G-Class.

The innovative anode material with a high silicon content will increase the energy density of batteries, Mercedes-Benz explains in a statement. Safety or other performance parameters would not be affected.

Specifically, Mercedes states, “Compared to today’s commercially available cells with a comparable format, Sila’s technology enables a 20-40% increase in energy density reaching more than 800 Wh/l at cell level.” Thanks to this development, the Stuttgart-based manufacturer will be able to store much more energy in the same space and thus significantly increase the range of future vehicles.

“Delivering such a high energy density is a true game changer and allows us to think in completely new directions when developing future electric cars,” says Markus Schäfer. As Chief Technology Officer, he is responsible for development and purchasing on the Board of Management of Mercedes-Benz Group AG. “Our partnership with Sila is another essential step on our way to build the most desirable electric luxury cars.” Sila will reportedly manufacture the silicon anode materials at its new plant in Washington state. Only renewable energy will be used in the process.

Mercedes-Benz is the factory’s first publicly named automotive customer. The two companies have set themselves the goal of equipping a version of the electric G-Class – Mercedes gave a preview of the XXL BEV last year with the Concept EQG – with increased range with the new battery technology option by the middle of the decade.

The connection between the two companies already has a small history: Mercedes-Benz had already invested in Sila in 2019. In 2018, BMW also agreed a partnership with the company.
