Mercedes-Benz said today that its engineers from the road and racetrack worked in collaboration with Factorial* cell engineers to deliver an all-new solid-state battery test program, resulting in the first car – a Mercedes-Benz EQS Sedan** – powered by a lithium-metal solid-state battery on the road.

“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.
