Title: Elucidating Electrochemical Energy Materials Through Versatile Electrochemistry

"In this seminar, I will discuss how new polymeric and low-dimensional materials, as well as an expanded electroanalytical toolbox for understanding interfaces, are allowing us to discover new synergies at the nano and mesoscale for emerging battery technologies. I will describe in detail one system where nano-scale heterogeneity has an impact on macro-scale performance: novel redox active polymers (RAPs) for size-selective flow batteries. Highly soluble RAPs are new players in redox flow technologies, and as part of our collaboration with the Joint Center for Research Energy Storage (JCESR), we are exploring the opportunities that macromolecular design offers for tuning their electrochemical performance. These investigations span across several areas of knowledge, from the interrogation of individual polymer particles, to the elucidation of new redox polyelectrolyte dynamics, and to the evaluation of flow battery performance. Finally, I will describe how we have applied insightful interfacial design and analysis to better understand other energy technologies such as ion batteries and electrocatalysts. Fundamental pursuit of electrode design principles have led us to investigate intercalation processes in low dimensional materials, and the use of ultra-thin electrodes for creating new charge transfer strategies on hetero-structures."
