Argonne researchers keep the discovery-to-industry pipeline moving by fabricating commercial-grade, prototype electrodes and battery cells in Argonne’s Cell Analysis, Modeling, and Prototyping facility, then testing the new materials in the Electrochemical Analysis and Diagnostics Laboratory. After standardized testing, the cell and electrodes are sent for advanced characterization and post-test analysis in Argonne’s Post-Test Facility, which entails dissecting, harvesting, and analyzing materials in an air-free environment. With knowledge of the causes of performance decline and/or failure, battery developers use this critical feedback to further improve batteries.
