Somerville-based battery maker Form Energy has leased nearly 100,000 square feet of space at 200 Inner Belt Road in East Somerville, reported by Boston Business Journal. The lease agreement is for three years, and the company plans to move its employees to the new location this fall. Form Energy also plans to extend the lease for its current space at 30 Dane St. in Somerville, part of the Somernova complex, for four years.  

The company aims to have all its Massachusetts employees under one roof or on the same campus in the next few years. Form Energy, known for its cost-effective iron-air battery technology, raised $450 million last year and is constructing its first manufacturing plant in West Virginia. The company has over 220 employees, with a significant portion hired in the past year.
