Argonne researchers design and synthesize candidate materials and assemble them into electrodes and test cells for characterization at a faster rate and greater depth than any other research institution in the world. Argonne has world-class facilities for material characterization, such as the Electrochemical Discovery Laboratory, Advanced Photon Source, and Center for Nanoscale Materials, where in-depth analysis is conducted before, during, and after the material has undergone cycling in test cells. Equally impressive are the capabilities for modeling to predict the properties of new or improved materials with extreme accuracy, which can be aided by the Argonne Leadership Computing Facility. These predictions then help to overcome materials shortcomings that arise throughout the discovery process.
