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