Koffi Pierre Yao is an Assistant Professor in the Department of Mechanical Engineering at the University of Delaware and Principal Investigator of LEAD.
Professor Yao’s research focuses on the design, fabrication, and characterization of energy materials for energy storage including Lithium-Ion, Sodium-Ion and Lithium-Sulfur, and conversion-based batteries. He is particularly interested in the development and utilization of operando electrochemical tools such as operando diffraction and spectroscopy for quasi real-time understanding of energy materials. His research interests are: (i) understanding of battery materials using operando synchrotron tools, (ii) understanding of degradation mechanics in conversion anodes for Lithium-Ion batteries in tandem with novel material design to mitigate these identified degradation pathways, (iii) developing novel electrolyte systems for suppression of polysufide shuttling in Lithium-Sulfur batteries, (iv) modeling of coupled transport and thermodynamics in ion-intercalation energy storage materials, (v) application of data science tools to energy material discovery and (vi) stochastic simulation of electric vehicle and grid interactions.
