Mercedes-Benz has unveiled a new solid-state battery that offers a 25 percent longer range in the EQS than the current battery. In the coming months, the manufacturer will conduct extensive laboratory and on-road testing to assess the durability and stability of solid-state batteries in real-world conditions.

The new solid-state battery, manufactured by American Factorial Energy, was installed in a modified EQS late last year, and thanks to it, the vehicle should have a range of more than 1,000 kilometers. This would be a significant improvement over the current 118 kWh battery in the EQS 450+, which allows a range of 800 kilometers on a single charge.

“Developing an automotive-scale solid-state battery underlines our commitment to innovation and sustainability. We’re therefore excited to announce that we’ve started road testing with a prototype vehicle equipped with this advanced technology. We will gain crucial insights into possible series integration of this cutting-edge battery technology,” said Markus Schäfer, Member of the Board of Management of Mercedes‑Benz Group AG.

Solid-state batteries use a solid electrolyte instead of a liquid one, and offer higher energy density and longer range without increasing the size and weight compared to lithium-ion batteries. They also increase cell safety and enable the use of new anodes such as lithium-metal anodes, and are also safer to use.
