摘要：

In this paper, helical mesoporous Ta2O5 nanotubes and Ta2O5/fluorine-doped carbon composite nanotubes (Ta2O5@C/F) (similar to 9 wt% of C and similar to 4 wt% of F) were prepared via a sol-gel method, using a chiral gelator as the template. Electrochemical studies showed that, the Ta2O5 nanotubes electrode and Ta2O5@C/F nanotubes electrode both possessed good Li-storage capability and cycling stability. The reversible capacity of Ta2O5@C/F was higher than that of Ta2O5, while the impedance of Ta2O5@C/F was lower than that of Ta2O5. These results indicated that the coating of fluorine-doped carbon layer could effectively improve the electrochemical performance of transition metal oxide anodes. (C) 2020 Elsevier B.V.
