Boston – King Street Properties announced that Ascend Elements, a company specializing in the production of sustainable lithium-ion battery materials, signed a lease for the new 101,000sf building located at 39 Jackson Road, part of King Street’s Pathway Devens campus. This transaction marks the full lease-up of the first phase of King Street’s Pathway Devens development.
