Factorial Delivers B-Samples of Lithium-Metal Solid-State Battery Cells to Mercedes-Benz

Exploring the Advancements in Solid-State Battery Technology

Factorial Inc., a prominent figure in solid-state battery technology development for electric vehicle (EV) applications, has recently disclosed the delivery of B-samples of its 106+Ah lithium-metal solid-state battery cells to Mercedes-Benz. This significant step signifies the first announced B-sample dispatch of solid-state battery cells to a global automotive original equipment manufacturer (OEM). This move highlights progress towards enhancing product maturity and preparing for the mass production of passenger EVs equipped with Factorial's cutting-edge solid-state battery technology.

Having already produced thousands of large-format solid-state batteries and supplied over 1,000 100+Ah solid-state battery cells to Mercedes-Benz in the A-sample phase, Factorial has demonstrated its ability to scale up the production of advanced battery cells efficiently. The B-samples will now undergo integration into modules and battery packs for extensive testing and optimization to validate designs against Mercedes-Benz's stringent performance specifications. This phase reinforces the reliability of Factorial's supply chain and manufacturing processes, ensuring scalability for future vehicle testing.

Factorial's solid-state batteries leverage the innovative FEST® (Factorial Electrolyte System Technology) platform, featuring a lithium-metal anode known for its lightweight properties that enable high energy density of 391Wh/kg. By utilizing existing equipment from lithium-ion battery production with minimal adjustments, Factorial can expedite the manufacturing validation process and significantly reduce long-term operational expenses.

Markus Schäfer, Chief Technology Officer at Mercedes-Benz Group AG, expressed the company's commitment to spearheading advancements in battery technologies, with the partnership with Factorial playing a vital role. The B-sample batteries provide an opportunity to further validate this next-generation technology to enhance range, performance, and reduce overall vehicle costs, ultimately offering customers the most desirable electric vehicles.

With joint development agreements in place with Stellantis and Hyundai Motor Company and Kia Corporation in addition to Mercedes-Benz, Factorial is solidifying its position as a crucial technology partner for leading automakers focusing on battery innovation to advance their EV portfolios.

Headquartered in the United States, Factorial aims to develop groundbreaking solid-state batteries that offer extended range per charge, enhanced safety, and competitive pricing compared to traditional lithium-ion batteries. The company's FEST® system utilizes a solid electrolyte material that has the potential to deliver reliable performance with high-capacity cathode and anode materials, working efficiently at room temperature and compatible with existing lithium-ion battery manufacturing equipment.
