dc.description.abstract | In this study, FeSe hollow spheroids were prepared for application as cathode electrocatalysts in Li-O-2 batteries. The hollow spheroids were synthesized through hydrothermal and thermal selenization processing based on a silk-fibroin template. At the high current rate of 1000 mA g(-1), the FeSe spheroids exhibited higher reversibility (100 cycles) and a similar voltage gap to that at 200 mA g(-1). Therefore, FeSe hollow spheroids exhibit high oxygen reduction/evolution catalytic efficiency for high-rate Li-O-2 batteries. This result was demonstrated via comparison of the oxygen reduction/evolution kinetics of FeSe and Fe2O3 hollow spheroids using electrochemical impedance spectroscopy. (C) 2020 Elsevier B.V.
