Summary:Single and polycrystalline CeO 2 nanorods (NRs) were prepared for application as oxygen-electrode electrocatalysts for lithium-oxygen batteries. The CeO 2 NRs were prepared via a time-controlled hydrothermal process. At a high current rate of 1000 mA g −1 , the single crystalline CeO 2 NRs exhibited a higher reversibility and a lower voltage gap than polycrystalline CeO 2 NRs. We compared the oxygen reduction and evolution kinetics of single and polycrystalline CeO 2 NRs using electrochemical impedance spectroscopy. Single crystalline CeO 2 nanorods electrocatalysts represent an excellent cycle reversibility for use in lithium-oxygen batteries.
