Mercedes-Benz takes another major step in building the world’s most desirable electric cars. Today, the inventor of the automobile announced that it will work with Sila, a next-generation battery materials company, 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. Moreover, it reaches more than 800 Wh/l at the cell level. This major development enables Mercedes-Benz to store more energy within the same space. Therefore, increasing the range of its future vehicles by a significant amount.
The advanced silicon anode materials will be manufactured using 100% renewable energy. That’s 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. They’re looking to equip it with the new battery technology option.
Mercedes-Benz invested in Sila in 2019. It did so as part of the company’s research and development of advanced batteries for the automaker’s future electric vehicles. The supply agreement announced today is the natural next step for the partnership. It marks another important milestone in Mercedes-Benz’s ambition to become the leading manufacturer of electric vehicles.
“Sila has come a long way since we established our strategic partnership in 2019. They have been proving their ability to not only deliver scientific innovation at the highest level but also their ability to manufacture high-quality material. We’re glad that in Sila we have a leading partner who will help us power our future generation of electric luxury vehicles with their highly innovative anode technology. 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. Our partnership with Sila is another essential step on our way to building the most desirable electric luxury cars,” said Markus Schäfer, Member of the Board of Management of Mercedes-Benz Group AG, Chief Technology Officer, responsible for Development and Procurement.
“We’re focused on delivering materials that are cost-efficient and capable of delivering on the promise of electric vehicles, working to ensure long-range energy, improved charge times, and lowering battery cost per kWh. To realize the potential of next-generation materials, scale-up is a pivotal part of execution and we’ve been building towards automotive quality standards and scale since our start. With our new plant in Washington, we’re ensuring we can meet the requirements of our auto partners like Mercedes-Benz as they transition to a fully electric future,” said Gene Berdichevsky, Co-founder, and CEO, of Sila.
Sila works to enhance all aspects of battery performance. The company produces quality-controlled silicon anode materials at scale. In addition, Sila supports implementation to ensure customers achieve their goals and safety requirements for shipping products. The Sila team was the first to industrialize and make commercially available a next-generation lithium-ion chemistry. Not to mention, with dramatically higher energy density. This expertise results in a technology that will be able to power future Mercedes-Benz electric vehicles.
