SHERIDAN, WYOMING – Mar 6, 2025 -In an impressive convergence of Formula 1 technology and automotive innovation, Mercedes AMG High Performance Powertrains (HPP) has announced a groundbreaking advancement in electric vehicle technology. In collaboration with the Mercedes Benz Center of Competence for Battery Systems and battery developer Factorial, Mercedes HPP is pioneering the development of a high-efficiency solid-state battery for road cars. This initiative represents a significant leap forward in sustainable automotive solutions.
The Genesis of Innovation
The journey to this innovation began with the synergistic efforts of Mercedes-Benz’s most skilled engineers, both from their road car division and Formula 1 team. The project capitalized on HPP's profound expertise in F1 technology, seamlessly adapting these high-performance technologies to consumer vehicles. The development focused on creating a lithium-metal solid-state battery that promises not only enhanced safety and longevity but also superior performance compared to traditional lithium-ion batteries.
From Lab to Road
The transition from theoretical design to tangible product underwent rigorous testing phases, which were conducted on various test benches throughout 2024. The culmination of these efforts was the successful integration of the prototype battery into a Mercedes EQS. This vehicle was specifically modified to accommodate the new battery technology, outfitted with all necessary accessories to support its functionality.
"The prototype underwent its initial laboratory tests in Stuttgart at the end of last year, setting the stage for road tests that commenced in February 2025," explained Markus Schäfer, a member of the Board of Management of Mercedes-Benz Group and CTO. "These tests are crucial as they provide invaluable data that will aid in the potential series integration of this technology."
A Leap in Battery Technology
The solid-state battery introduced by Mercedes promises to revolutionize the electric vehicle industry by significantly increasing the gravimetric energy density up to 450 Wh/kg at the cell level. This innovation allows the battery to deliver up to 25% more driving range than the current standard EQS battery of the same weight and size, which is equipped with traditional battery technology.
Moreover, this cutting-edge battery system incorporates passive cooling mechanisms that enhance energy efficiency without the added bulk of active cooling components. The prototype vehicle equipped with this technology is expected to achieve a driving range of over 1,000km (approximately 620 miles) on a single charge, a stark improvement over existing models.
Forward-Looking Statements
"Developing an automotive-scale solid-state battery underlines our commitment to innovation and sustainability," Schäfer noted. "We are excited to move forward with road testing a prototype vehicle equipped with this advanced technology. This will provide us with crucial insights into the integration of solid-state batteries into future production models."
As Mercedes AMG HPP continues to test and refine this technology, the potential for its commercial application grows, signaling a transformative era in electric mobility. This development not only underscores Mercedes-Benz’s leadership in automotive innovation but also reinforces its dedication to pioneering sustainable, high-performance solutions that meet the demands of modern consumers.
