Biography
Tadhg studied Pharmaceutical and Industrial Chemistry at undergraduate level before obtaining his PhD in Chemistry in the University of Limerick. He is currently a lecturer in the Department of Chemical and Environmental Sciences where his teaching interests lie in physical, analytical and inorganic chemistry.
Tadhg's research involves the development of high-capacity electrode materials for energy storage devices. His primary focus is on the application of nanostructured semiconductor anodes for next-generation lithium-ion batteries. He has considerable experience in the development of low-cost synthetic methods for lithium-alloying electrodes based on Si and Ge and the enhancement of their cycling performance through morphology control and electrolyte optimisation. Tadhg is currently involved in a large scale collaborative project with the FP7 involving 17 EU partners known as the Greenlion project with the main objective being the manufacture of greener and cheaper lithium-ion batteries for electric vehicle applications.
