Abstract

Single and polycrystalline CeO2 nanorods (NRs) were prepared for application as oxygen-electrode electrocatalysts for lithium-oxygen batteries. The CeO2 NRs were prepared via a time-controlled hydrothermal process. At a high current rate of 1000 mA g-1, the single crystalline CeO2 NRs exhibited a higher reversibility and a lower voltage gap than polycrystalline CeO2 NRs. We compared the oxygen reduction and evolution kinetics of single and polycrystalline CeO2 NRs using electrochemical impedance spectroscopy.
