Solid-state EV batteries are on the way — Mercedes’ partner plans deliveries by 2025
Solid-state EV batteries will be here before you know it, Mercedes-backed Farasis Energy claims. During a recent investor meeting, Farasis said it will begin delivering solid-state EV batteries by the end of 2025.
Farasis Energy will deliver solid-state EV batteries in 2025
The new battery tech, promising to unlock more driving range, faster charging, and longer life-spans, is finally moving from the lab to the real world.
Farasis Energy confirmed during the meeting, held on September 15, that its all-solid-state EV batteries are now entering pilot production and delivery. The company is building a 0.2 GWh pilot line for the new sulfide-based solid-state batteries, with deliveries set to begin by the end of 2025.
In a filing released the following day, viewed by IT Home, the company said it’s fully committed to bringing the new battery tech to market.
Farasis uses a high-nickel ternary cathode and a high-silicon anode, claiming an energy density of 400 to 500 Wh/kg.
The report said R&D has progressed “smoothly,” and the company plans to begin deliveries by the end of 2025. Initially, they will be delivered in small batches to select customers.
Meanwhile, Farasis’ second-gen sulfide-based all-solid-state EV batteries are moving past the tech development phase. The second-gen batteries have an energy density of 500 Wh/kg, which would be among the highest in the industry. It’s expected to roll out in 2026.
In 2027, the company plans to launch the third-generation, promising to unlock an energy density of over 500 Wh/kg.
The report claims that the semi-solid-state batteries only cost 5% to 10% more than liquid batteries, and Farasis expects shipments to ramp up significantly next year.
Just this year, Farasis Energy said it has secured new clients, including XPeng, GAC Group, and “a leading domestic new energy commercial vehicle client” for its core products, SPS (Super Pouch Solution) batteries, and semi-solid state batteries.
The company plans to expand overseas and into new segments, including humanoid robots. Farasis is already using all-solid-state batteries in humanoid robots and has sent samples to leading humanoid robot companies.
Mercedes-Benz bought a stake in Farasis Energy in 2020 to secure battery supply for its upcoming electric vehicles.
The news comes after Mercedes announced just last week that it drove an EQS, equipped with solid-state batteries, from Stuttgart, Germany, to Malmö, Sweden, covering 750 miles (1,205 km). Mercedes said the vehicle still had another 85 miles of range to go. US-based Factorial Energy supplied the battery cells.
Mercedes’ tech boss, Markus Schäfer, called solid-state batteries “a true gamechanger” for electric vehicles. Schäfer added the new battery tech “delivers not only in the lab but also on the road.”
Farasis Energy, Mercedes-Benz, and Factorial Energy are just a few of the companies racing to unlock the “holy grail” of EV batteries. Toyota, Volkswagen, Stellantis, and Honda, to name a few, are aiming to launch solid-state batteries by the end of the decade. BYD and CATL are reportedly aiming for around 2027.
Earlier this week, SK On said it plans to commercialize all-solid-state batteries by 2029, a year ahead of schedule.
