In this research, the novel one-dimensional mesoporous NaTi2(PO4)3@C fibers (abbreviated as C-NTP-1D) are synthesized via an electrospinning method to promote the rate capability of pristine NaTi2(PO4)3 (NTP). The electrochemical properties, crystal structure and morphology for the resulted fibers have been explored by various electrochemical testing techniques, XRD, XPS, Raman spectroscopy, SEM as well as TEM. Benefiting from the designed mesoporous structure, the C-NTP-1D anode displays superior electrochemical properties. The specific capacities of 130.1 and 117.7 mAh g−1 is achieved at 0.1 and 2 C, and the C-NTP-1D presents the high capability of 89.1 mAh g−1 at 10 C following 500-cycle spans. Therefore, the designed mesoporous C-NTP-1D nanofibers can find potential applications as novel electrode for sodium-ion batteries.
