Boise State University Theses and Dissertations

This dissertation investigates the fundamental understanding in the influences of order-disorder and atomic arrangement on electrochemical properties of electrode materials for sodium ion batteries (SIBs). In specific, TiO₂ anode and NaNi_xFe_yMn_xO₂ cathode materials are studied. Due to their low cost and relatively high abundance of raw materials SIBs are attractive for large-scale energy storage systems for high round trip efficiency and long cycle life. Recent studies suggest that various polymorphs of TiO₂ are suitable as anode material. However, the impact of crystallinity on the electrochemical properties of the material has not …
