Rechargeable batteries are promising energy storage technologies to provide high energy and high power for applications such as electric vehicles and electrical grids. Recent studies have observed that electrode materials (e.g., TiO2) containing intentional structural defects exhibit enhanced electrochemical charge storage capacity. In the first part of this talk I will introduce our work on the irradiation effect on structure and electrochemical response of TiO2 nanostructured electrodes through room-temperature and 250 C proton irradiations as irradiation is known to produce an excess of defects in a material. The defect generation upon irradiation and changes in electrochemical response in nanostructured TiO2 samples in lithium-ion batteries will be discussed. In the second half of this talk the work on defect-driven nanostructured niobium oxide electrodes for their use as anode for lithium-ion batteries will be discussed.
