Mercedes-Benz to incorporate Sila’s Si anode chemistry in batteries for the electric G-Class; > 800 Wh/l on cell level

Mercedes-Benz will work with Sila, a next-generation battery materials company (earlier post), to incorporate Sila's silicon anode chemistry in batteries which are optionally available for the first time in the upcoming electric Mercedes-Benz G-Class. This will add another innovative cell chemistry to the Mercedes-Benz battery portfolio.

The innovative high-silicon anode material will increase the energy density of batteries without compromising safety or other performance parameters. 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. This major development enables Mercedes-Benz to store more energy within the same space, thus increasing range of its future vehicles by a significant amount.

The advanced silicon anode materials will be manufactured using 100% renewable energy in Sila’s new Washington state facility, making Mercedes-Benz the factory’s first publicly announced automotive customer. Both companies are targeting mid-decade for a range-extended-version of the electric G-Class to be equipped with the new battery technology option.

Mercedes-Benz invested in Sila in 2019 as part of the company’s research and development of advanced batteries for the automaker’s future electric vehicles. The supply agreement is the natural next step for the partnership.



I might be interrested to buy if this silicone anode is licensed to cheap chinese bevs and forget hydrogen because hydrogen is late, especially in north-america. I heve to hurry before 2030 as gasoline is too costly.


Interesting to see the pros an cons of Si anode versus Graphite anode and others... many graphite mines and their vertical integration are assuming they will be part of this industry for at least this decade...
