Energy company Farasis, supported by Mercedes-Benz, initiates the pilot manufacturing of solid-state batteries, with a production line of 0.2 gigawatt-hours scheduled for completion by the end of the year.
Farasis Energy, a leading battery manufacturer with backing from Geely, Togg, Mercedes-Benz, and others, has entered the pilot production phase of its sulfide-based solid-state batteries as of mid-2025. The company's pilot production line, boasting a design capacity of 0.2 GWh, is expected to be completed by the end of 2025.
The technology behind these solid-state batteries focuses on sulfide-based solid electrolytes combined with high-nickel cathodes and high-silicon or lithium metal anodes, aiming for an energy density exceeding 400 Wh/kg. These cells have been tested in real-world conditions and have demonstrated stable cycling performance and robust safety features, including resistance to puncture, shear, and heat, as well as integrated thermal runaway shutdown systems.
Beyond the pilot phase, Farasis intends to scale solid-state battery production to gigawatt-hour (GWh) levels in 2026, signaling a shift to full industrialization within a year after pilot production begins. There is also rising interest from electric vehicle manufacturers beyond its existing partners, prompting plans for broader sample deliveries and partnership expansion.
Mercedes-Benz holds a strategic stake in Farasis (3% since 2020), aligning with their long-term commitment to advanced battery technology for electric vehicles. Farasis currently supplies batteries for Mercedes models like the EQE and EQS and is pushing forward on next-generation solid-state battery tech that could notably enhance EV performance and safety by replacing traditional liquid electrolytes with solid sulfide compounds.
In summary, Farasis Energy's pilot production of sulfide-based solid-state batteries marks a significant step forward in the development of advanced EV batteries. With ambitious scaling goals and a premium automaker partner, Farasis is well-positioned to lead the charge in this exciting field.
