Silicon anode firms secure raw materials

Sila Nanotechnologies and Group 14 Technologies are securing high-purity silane gas to make silicon-based battery anodes—Sila through a contract and Group14 with its own plant. Both companies are building anode plants in Moses Lake, Washington. Sila has signed a supply agreement with REC Silicon, which produces silane at a facility in Moses Lake. REC had previously inked commitments to supply much of its silane to solar panel makers. Meanwhile, Group14 received a US Department of Energy grant to build its own silane plant in Washington.
