Electric Mercedes G-Class SUV due to high power-density silicon anode power

An upcoming electric version of the Mercedes-Benz G-Class SUV will use silicon anode battery chemistry from American firm Sila, Mercedes confirmed in a press release on Tuesday.

Founded in 2011, Sila claims that its high-silicon anode material can increase energy concentration by 20% to 40% compared to current lithium-ion cell chemistry. The high power concentration allows more energy to be stored in a specific location, helping to increase the range without enlarging the battery pack.

Mercedes, which invested in Seala in 2019, plans to use the company’s cells in the mid-decade for an extended-range version of the Electric G-Class. The cells will come from a factory in Washington state using 100% renewable energy, the companies claimed.

Mercedes is the first universally announced autonomous customer for the factory, and plans to expand the use of the new chemistry to other models after its debut in the G-Class.

The G-Class EV was first teased in 2019 and officially confirmed in 2021. It is currently slated to launch in 2024.

Mercedes previewed the electric G-Class with last year’s EQG concept, which was not seen too far in the development cycle. The idea was to place its battery modules in a ladder frame similar to the current G-Class and had four electric motors – one for each wheel. A removable 2-speed gearbox handles off-road gear reduction.

When the concept was unveiled, Mercedes said it planned an off-road trial for later production-intended versions. They will be taken to the 4,4741-foot Shockle Mountain in Graz, Austria, where there is a 3.5-mile off-road course with a gradient up to 60 degrees.

Like the standard G-Class, the electronic version will be the toughest entry in a larger lineup. Mercedes plans to launch fully electric in some markets by 2030, enabled by three dedicated EV platforms to be launched in 2025.
