Factorial Energy Opens Major Battery Facility in Methuen, MA

Factorial Energy, the US developer of solid-state battery cells backed by Mercedes-Benz, Stellantis and Hyundai-Kia, has opened its manufacturing facility in Methuen, a Massachusetts suburb of Boston. It has space to assemble batteries with an annual capacity of up to 200 MWh and is expected to create 150 jobs.

The 200 MWh factory will be the largest solid-state battery assembly line in the U.S.

Thanks to the Manufacturing Production Tax Credit (45X), Factorial will build its solid-state battery cells here in the U.S., bolstering the domestic supply chain for critical minerals and batteries. The company invested 50 million dollars in the facility – around five million more than planned. Factorial is also behind its announced schedule. Initially, the plant was to be operational by early 2023. The approximately 6,225-square-foot building houses a pilot production facility for its solid-state batteries. Factorial first announced the construction of the facility in August 2022.
