Mercedes AMG High Performance Powertrains (HPP) and the Mercedes-Benz Competence Center for Battery Systems have developed a new solid-state battery system that uses corresponding cells from partner Factorial Energy. A lithium-metal solid-state battery has been installed in a modified Mercedes-Benz EQS, and after laboratory tests, it will be tested on the road from February 2025. The weight and size should be comparable to the 118 kWh standard battery of an EQS. However, it should enable a range of over 1,000 km, up to 25% higher than before.
The prototype of a solid-state battery with cells from Factorial Energy features, among other things, an innovative, floating cell carrier. Pneumatic actuators react to changes in cell volume during charging and discharging. This is intended to optimize the battery's performance and lifespan. In addition, a passive battery cooling system is integrated. In the coming months, the solid-state battery is to be tested in further laboratory and road tests. Mercedes-Benz and Factorial have been working together since 2021.
