Factorial Energy opens new solid-state battery manufacturing facility

Factorial announced the opening of its new battery manufacturing facility in the Boston suburb of Methuen, Mass. The facility represents a significant step in scaling up the production of Factorial’s solid-state battery technology for EVs.

The new facility represents a $50-million investment and is expected to create more than 150 local jobs. Located in the greater Boston area, Factorial’s operations remain close to its newly opened R&D facility and corporate headquarters advancing the production of Factorial’s solid-state battery technology for its automotive partners.

The current footprint will accommodate up to a 200MWh assembly line, which is expected to be the largest solid-state battery assembly line in the US.

Factorial’s proprietary FEST (Factorial Electrolyte System Technology) quasi-solid-state batteries are designed for higher energy density and safety compared to lithium-ion batteries. FEST leverages a solid electrolyte material, which has the potential to enable safe and reliable cell performance with high-capacity cathode and anode materials.

Earlier in October, Factorial delivered A-samples of its 100+Ah solid-state EV battery cells to global automotive OEM partners for testing. A step towards serial production, the 100+Ah lithium-metal battery cells are automotive-sized to meet key performance requirements. This makes this the first global shipment of 100+Ah lithium-metal cells to pass UN 38.3 safety tests.

Factorial has entered into joint development agreements with Mercedes-Benz, Stellantis, and Hyundai Motor Company.
