Factorial Energy specializes in the development of solid-state batteries designed to enhance safety and performance within the electric vehicle and energy storage sectors. Established in Massachusetts, the company’s focus lies in creating innovative battery solutions that address the limitations of traditional lithium-ion technologies. Their proprietary FEST® (Factorial Electrolyte System Technology) and Solstice™ platforms leverage solid electrolytes, representing a notable advancement in battery technology.
Battery Technology
Factorial Energy’s solid-state battery innovations focus around the FEST® platform and Solstice™ technology. The FEST® system utilizes a lithium-metal anode in conjunction with a proprietary solid electrolyte, achieving energy densities as high as 390 Wh/kg. This setup removes the requirement for liquid electrolytes, vastly enhancing safety and reliability.
The Solstice™ platform, developed alongside Mercedes-Benz, signifies a leap forward in solid-state innovation, attaining energy densities up to 450 Wh/kg. It incorporates a groundbreaking dry cathode coating process that eliminates harmful solvents from manufacturing, thus minimizing environmental impact. This technology is compatible with existing battery production lines, facilitating efficient scalability in manufacturing processes.
Both platforms outshine conventional lithium-ion batteries by offering superior thermal stability, quicker charging times, and longer cycle life. The solid-state architecture prevents thermal runaway incidents, effectively addressing the safety challenges linked to earlier battery technologies.
Recent Projects
In 2024, Factorial Energy entered a partnership with Stellantis to create a demonstration fleet of Dodge Charger Daytona vehicles outfitted with FEST® solid-state batteries. This initiative, scheduled for 2026, aims to assess the technology’s performance in real-world conditions. Additionally, the company has increased its production capacity by unveiling 40Ah all-solid-state battery cells produced through their innovative dry coating technique.
Investors
Factorial Energy has attracted significant investment from top automotive brands, including Mercedes-Benz, Stellantis NV, Hyundai Motor Company, and Kia Corporation. These strategic collaborations involve joint development agreements aimed at furthering the growth and market introduction of solid-state battery technologies. While maintaining independent operations, the company benefits from the technical prowess and resources provided by its automotive partners.
