US-based solid-state battery technology company Factorial Energy has entered into joint collaboration agreements with both Mercedes-Benz and Stellantis N.V. each of whom is also making a strategic investment in the company.
“These partnerships will accelerate our ability to commercialize our core technology,” said Factorial Energy CEO Siyu Huang, Ph.D. “With our new partners we can develop batteries that not only enable safer and longer driving range vehicles, but that are also compatible with conventional lithium-ion battery manufacturing environments.”
Factorial’s technology offers a high level of operational safety and extends driving range by 20 to 50 percent, addressing two key factors to broad consumer adoption. Its drop-in compatibility with existing lithium-ion battery manufacturing infrastructure reduces costs and the complexity of changing to a different battery technology for auto manufacturers.
“By accelerating our Mercedes-Benz strategy towards ‘Electric Only’, we have set the course for a fully electric future. We will also play a leading role in the field of battery technology. With Factorial as our new partner, we are taking research and development in the field of promising solid-state batteries to the next level. To this end, we are investing a high double-digit million dollar amount in Factorial,” said Markus Schäfer, Member of the Board of Management of Daimler AG and Mercedes-Benz AG and responsible for Daimler Group Research and Mercedes-Benz Cars COO. “With this cooperation, we combine Mercedes-Benz’s expertise in battery development and vehicle integration with the comprehensive know-how of our partner Factorial in the field of solid-state batteries. We share the common vision of CO2 neutrality. The continuous development of innovative battery technologies will make electric mobility even more attractive for our customers.”
Factorial’s advances are based on FEST (Factorial Electrolyte System Technology), which leverages a proprietary solid electrolyte material that enables safe and reliable cell performance with high-voltage and high-capacity electrodes at room temperature. Earlier this year, Factorial became the first to reach the 40 Amp-hour benchmark with a solid-state cell that works at room temperature, demonstrating the scalability of the FEST electrolyte.
“Our investment in Factorial and other highly recognized battery partners boosts the speed and agility needed to provide cutting-edge technology for our electric vehicle portfolio,” said Stellantis CEO Carlos Tavares. “Initiatives like these will yield a faster time to market and more cost-effective transition to solid-state technology.”
Factorial’s collaboration agreements with leading global automotive manufacturers, including Hyundai Motor Company, Kia Corporation, Stellantis and Mercedes-Benz, are a significant validation of its technology and a springboard for commercialization in vehicles around the world.
