Energy storage in the electrochemical form is attractive because of its high efficiency and fast response time. New and improved materials for energy storage are urgently required to make more efficient use of our finite supply of fossil fuels, and to enable the effective use of renewable energy sources. In this seminar, I will discuss a few new perspectives for energy storage materials including new Li intercalation compounds, new Na intercalation compounds and their micro and nanostructured electrodes. I will demonstrate how to combine knowledge-guided synthesis/characterization and first principles computation to develop and optimize new higher energy/power density electrode materials for lithium ion and sodium ion batteries. With recent advances in characterization tools and computational methods, we are able to explore intrinsic ionic mobility and phase transformations in electrode materials, and develop an approach to map out the structure-properties relations in functional materials for energy storage and conversion.
