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. Lithium ion batteries are a key source for mobile energy and one of the most promising solutions for environment-friendly transportation. However the state-of-art electrode materials for lithium ion batteries are cobalt based oxides, which are expensive, introduce safety issues and have poor rate capability for high power applications (such as plug-in HEV). I will demonstrate how to combine knowledge-guided synthesis/characterization and ab initio computation to develop and optimize new higher energy/power density cathode materials. In addition, with advances in controlled synthesis of nanomaterials, we are able to explore intrinsic ionic diffusivity and phase transformations in nanomaterials, developing a new approach to understand thermodynamic and transport properties of functional nanomaterials for energy storage and conversion.
