Mercedes-Benz has started testing its new generation of electric vehicles using solid-state battery technology on the roads. When we look at the first trials, it is said that the range increased by 25% on a single charge in tests on the EQS model and exceeded the 1000 km limit. Here are the details…
Mercedes starts testing solid-state battery electric vehicle: 25% more range!
The new battery systems that have begun testing use solid electrolyte cells developed by Factorial Energy. Developed by Mercedes in partnership with the Formula 1 technology team, the batteries have a higher energy density than conventional lithium-ion batteries.

The new system aims to be the best in its class by reaching an energy density of 450 Wh/kg. As you know, solid-state batteries offer a safer use as they eliminate the risk of liquid electrolyte leakage. In addition, the fact that it can operate without the need for an active cooling system increases efficiency by reducing the weight of the vehicle.
Mercedes will first test the new battery system with the EQS model, and plans to use it in its entire electric vehicle range in the coming years. The company announced that after completing laboratory tests in 2024, it switched to road trials and is working quickly to commercialize the technology.
What do you think about this? Do you think solid-state battery technology will change the future of electric vehicles? What advantage would a 1000 km range Mercedes EQS have over Tesla and other competitors? You can write your opinions in the comments section below…
