Understanding the crystal chemistry of ionic diffusion through polyanionic intercalation hosts

Seminar | February 24 | 4-5 p.m. |  Pitzer Auditorium, 120 Latimer Hall

 Prof. Brent Melot, Department of Chemistry, University of Southern California

 College of Chemistry

The most important problem the world faces is how to establish a sustainable energy infrastructure. A critical component to this challenge is how to safely store large amounts of energy in an economically viable way. While a large body of work has been dedicated to identifying new intercalation hosts for Li-ion batteries, a fundamental understanding of the mechanism for ionic diffusion through many materials is lacking. In this talk, a general strategy for the design of new insertion electrodes will be presented with a focus on our group’s efforts to develop new electrode materials using Earth-abundant and non-toxic elements like Fe and SiO2.

 Light refreshments will be served at 3:50pm in The Coffee Lab
