Factorial Inc., a Massachusetts-based solid-state battery developer, has announced the shipment of its energy-dense B-sample solid-state battery cells to Mercedes-Benz as part of their joint development agreement. This marks a significant step forward in the validation of Factorial’s solid-state battery technology for integration into future passenger electric vehicles (EVs) by Mercedes-Benz.
The Factorial Electrolyte System Technology (FEST) solid-state cells, with a capacity of over 100 Amp-hours (Ah), are designed to be compatible with existing lithium-ion battery manufacturing equipment, streamlining their integration into EV production lines. The cells have already received UN certification, and A-samples were sent to original equipment manufacturer (OEM) partners in October 2023.
Factorial’s latest shipment of B-sample cells to Mercedes-Benz represents a crucial milestone in their partnership. Over 1,000 of these high-energy-density cells have been delivered to Mercedes-Benz for testing and integration into EV modules and battery packs. Factorial’s CEO, Siyu Huang, highlighted the company’s commitment to accelerating the adoption of solid-state batteries, stating, “This swift progression from A-sample to B-sample delivery in under a year highlights Factorialâs rapid innovation capabilities.”
Mercedes-Benz, in its pursuit of innovative battery technologies, views the collaboration with Factorial as a strategic move towards enhancing range and performance, reducing vehicle costs, and offering more desirable electric vehicles to customers. Markus SchĂ€fer, CTO and member of the board of Management at Mercedes-Benz Group AG, emphasized the importance of this partnership, stating, “These B-sample batteries give us the opportunity to further validate this next-generation battery technology.”
Beyond Mercedes-Benz, Factorial has joint development agreements with Stellantis, Hyundai Motor Company, and Kia Corporation, indicating broader industry interest in their solid-state battery technology. While there is no timeline for when other OEMs will receive B-sample cells, the company remains committed to advancing the integration of solid-state batteries into the EV market.
