Factorial, a developer of solid-state battery technology for electric vehicle (EV) applications, announced the delivery of B-samples of its 106+Ah lithium-metal solid-state battery cells to Mercedes-Benz as part of their ongoing joint development agreement.
This milestone marks the world’s first announced B-sample shipment of solid-state battery cells to a global automotive OEM, showcasing progress toward product maturity and the series production of passenger EVs equipped with Factorial’s solid-state battery technology.
Factorial has manufactured thousands of large-format solid-state batteries and shipped over 1,000 100+Ah solid-state battery cells to Mercedes-Benz as part of the A-sample phase, highlighting its capacity to produce high volumes of advanced battery cells. The B-samples will be integrated into modules and battery packs for extensive testing and optimization.
This crucial phase involves validating the module and pack designs against Mercedes-Benz’s strict performance specifications. Additionally, this step will confirm the robustness of Factorial’s supply chain and its manufacturing processes, ensuring scalability for future vehicle testing.
The solid-state battery cells use Factorial’s proprietary FEST (Factorial Electrolyte System Technology) platform that includes a lithium-metal anode, which is the lightest metal on earth and enables the high-energy density of 391Wh/kg. Factorial’s batteries are manufactured using existing equipment from lithium-ion battery production, requiring minimal modifications. This approach can streamline the manufacturing validation process and significantly reduce long-term operating costs.
“We are committed to leading in innovative battery technologies, and our partnership with Factorial is a significant part of this strategy,” said Markus Schäfer, member of the Board of Management at Mercedes-Benz Group AG, Chief Technology Officer. “These B-sample batteries give us the opportunity to further validate this next-generation battery technology with the goal of enhancing range and performance, reducing overall vehicle costs, and offering the most desirable electric vehicles to our customers.”
This milestone establishes Factorial as a pivotal technology partner for leading automakers pursuing battery innovation to advance their EV portfolios. In addition to Mercedes-Benz, Factorial has joint development agreements with Stellantis and Hyundai Motor Company and Kia Corporation.
