Mercedes revealed semi-solid-state batteries

Solid-State Batteries Stay many years from auto showrooms. The automobile industry was chased by batterythat replaces the liquid electrolytes with a strong ceramic or material glass, due to their potential to bring more powerful, violent and improved Vehicle Safety by reducing the flammability of other types of lithium-ion batteries.

Now, Mercedes-Benz and the stable battery of the State factory reaches an optimistic half point, strapping semi-Solid-State cells at the main electric electric sedan.

Mercedes announced that this test was started on the road prototype cells in this EQS full-seded sedan. Woburn, based on Massachusetts Active energy Cells provide format format, and co-develops pack Mercedes-Amg High Prefation PowertrainsThe Automaker’s Formula 1 Brixworth’s career subsidiary, UK

Mercedes says the battery delivers a real world driving more than 1,000 kilometers (620 miles), about 25 percent more than one usual Lithium Nickel Muanese Coxide Oxide battery of the same size and mass. For comparison, the 2025 EQS 450+ Current marked 800 kilometers (497 miles) in the shedding world hamming the US protection lights at 390

Mercedes and factorials speak semi- (or “quasi-“) battery in the state-state state is the first jump to the laboratory banks. Mercedes began to conduct stuttgart lab tests at the end of 2024 before starting the streets test in February.

“The first successful join lithium-metal Solid-State Batteries In a production vehicle marks a historical success in electric movility, “says Siyu Huang, CEO and co-founder with strong strength.

Huang says fest cells (for “Electrolyte System Technology“) About a strong Energy energy to 391 watt-hours per kilogram. Comparing 300 wh / kg / kg or less for current leading high-nickel cells. 106 amp-time cells have a Solid Electrolyte infused with gel or liquid. Factorial is also developing a solid “solt-state” with a Sulfpide electrolyte target to 500 cell levels, up to 80 percent higher driving. That 500 wh / kg double-high-nickel batteries, and about 2.5 times well as the best batteries of irithium iron phosphate.

“That’s a long limit where the steady state goes,” said Huang.

So automakers can be pully now battery packs now in half size, weight and capacity – while delivering the same range range; or keep packages like the same size as the powerful force or performance. Clearly downsized packs will make a chain of engineering acquisitions including harsh chassis, suspensions, cooling systems, and other components of batteries and carriages.

At first, Huang believes the tech suits the premium and high-performance cars, as a better choice in high-nickel cells. The company also sees the potential for Consumer devices,, reedor sea applications with serious electricity demands.

Just as important as performance profits, cells cells are in accordance with existing Lithium-ion battery Create, according to Huang, who saw 846 Gigawatt-time In the cells deployed in the world of electric vehicles in 2024 Huang estimates a battery maker that a 1-gigawatt factory can change the solid solid state for small US $ 10 million.

“So it’s easier to ramp, not just for doing, but to progress in the crop and cost reduction,” said Huang.

The reason for the moment has a hoof’s access for 500,000 fest cells per year, and detects the battery consequences that should have a pilot measure that has to have a pilot’s measure. The companythat raises $ 200 million in a fund led by Mercedes and Stellantis, also supplied fests cells for a Demonstration Armada In Dodge Charger Daytonas. Those electric cars are expected to hit the streets of 2026. The Carger Daytona is one of many electrified models from Alfa Romeo, ChryslerDodge, Jeepand Maserati built in stellantis’ Stla plus platuridado.

Also allowed in solid-state-state design for an anitium-metal anode that replaces generic and brings out more energy. Mercedes battery is also important for patent “floating carrier cells.” Pouch cells expand during charging, and contract during discharge. The Division of F1 Mercedes develops a flexible carrier to manage the changes in volume, with Pneumatic actuators To help keep the right pressing inside cells.

“There is like a ‘breathing behavior’ during the cell cycling,” said Huang. “So you need a system to take care of breathing and make it more efficient in the whole life, while still increasing energy efficiency.”

As for solstice batteries across the state, the fact that there is a 100 per cent process of dry-ups of all hazardous coating coating. Carcinogenic solvents now require strong evaporation of safe recycling them. Design also caused the process of flowing energy “formula” where newly conjunctive cells should be charged and charged to activate electrolyte materials. Together, dry cloth and cell design promises more lasting battery production with minimal cost and environmental effect.

Factory batteries are one among the promising improvements in solid state. Volkswagen shares the cup of Silicon Valley. Colorado’s strong power has a combined development of progress BMW. Honda Just opened a demonstration line of state production Sakura in Sakura, J’Tan. Toyota also develops cell-state cells at home, about a $ 13.6 billion investments In Battery R & D.

Like some experts, Huang saw 2030 as a viable target for a tech that could ARS Go forward, charging faster and becomes more cheaper.

“I think there is potential to see these batteries in the showrooms at the end of the decade,” said Huang.
