Mercedes-Benz has reached a major milestone by testing the world’s first electric vehicle (EV) powered by a solid-state battery. This revolutionary technology, developed in collaboration with US-based Factorial Energy, is expected to provide a significant boost in EV performance, offering a driving range of over 621 miles.
The test vehicle, a modified version of the EQS, marks the transition of solid-state battery technology from laboratory testing to real-world application. This breakthrough technology offers increased energy density, improved safety, and faster charging times, providing a glimpse into the future of electric mobility.
Mercedes-Benz has been working with Factorial Energy since 2021, with the goal of improving battery efficiency and driving range. The newly developed Solstice battery, which utilizes a sulphide-based solid electrolyte, promises 80% more driving range than traditional lithium-ion batteries, thanks to its breakthrough energy density of 450 Wh/kg.
The collaboration has led to the creation of a new battery pack designed by Mercedes and Mercedes AMG High-Performance Powertrains (HPP), which is also a key supplier to Formula 1. The solid-state batteries are expected to deliver a 25% increase in the driving range of the EQS, potentially pushing it beyond 620 miles.
With specifications still being finalized, this new technology is poised to play a key role in Mercedes’ upcoming EV models. As the automotive industry moves towards more sustainable solutions, Mercedes-Benz’s solid-state battery technology represents a significant step forward in the quest for cleaner, more efficient electric vehicles.
