Donal Finegan is a staff scientist at the NREL Center for Integrated Mobility Systems. His work focuses on understanding degradation and failure mechanisms of Li-ion batteries and taking steps to improve the performance and safety of cells and battery systems. His research has spanned numerous conventional and next generation energy-storage materials, such as various transition metal oxides, silicon, graphites, composite electrodes, and sulfur-based solid electrolytes. He is a frequent user of international synchrotron facilities and has pioneered the application of high-speed X-ray imaging for diagnosing battery failure mechanisms during thermal runaway. He actively engages with industry, research institutions and universities. He is a visiting lecturer at University College London (UCL), has published over 50 journal articles, and his work has received several internationally recognized awards.
