The Critical Materials Institute (CMI), an Energy Innovation Hub established in 2013 and led by Ames Laboratory, is a sustained, multidisciplinary effort to develop solutions across the materials life cycle as well as reduce the impact of supply chain disruptions and price fluctuations associated with these valuable resources.

By bringing together scientists and engineers from diverse disciplines, the CMI is addressing challenges in critical materials, including mineral processing, manufacture, substitution, efficient use, and end-of-life recycling; integrating scientific research, engineering innovation, manufacturing and process improvements; and developing a holistic solution to the materials challenges facing the nation.

It includes expertise from four national laboratories, seven universities, and ten industry partners to minimize materials criticality as an impediment to the commercialization of clean energy technologies.
