Factorial Energy’s FEST® platform utilizes a lithium-metal anode and proprietary solid electrolyte, achieving energy densities up to 390 Wh/kg and eliminating liquid electrolytes for enhanced safety and reliability. The Solstice™ platform, developed with Mercedes-Benz, attains energy densities up to 450 Wh/kg via a dry cathode coating process that removes harmful solvents and is compatible with existing production lines, enabling scalable manufacturing. Both platforms offer superior thermal stability, faster charging, longer cycle life, and prevent thermal runaway incidents compared to conventional lithium-ion batteries.
FEST® solid-state batteries featuring a lithium-metal anode, proprietary solid electrolyte, and energy density up to 390 Wh/kg; Solstice™ solid-state batteries with a dry cathode coating process, energy density up to 450 Wh/kg, and existing line compatibility; 40Ah all-solid-state battery cells produced via the dry coating technique.
2024 partnership with Stellantis to deploy a demonstration fleet of Dodge Charger Daytona vehicles equipped with FEST® solid-state batteries for real-world testing, scheduled for 2026. Unveiling of 40Ah all-solid-state battery cells produced through the company’s dry coating technique to expand production capacity.
Backed by Mercedes-Benz, Stellantis NV, Hyundai Motor Company, and Kia Corporation through strategic investments and joint development agreements to advance solid-state battery commercialization, while maintaining independent operations.
