TiO2-based nanostructure has been reported as one of the most developable anode materials for sodium-ion batteries, but its low capacity and poor rate capability bring an unavoidable challenge and impede the practical application. In this study, surface phosphorylated TiO2nanofibers with anatase/bronze binary-phase are fabricated using ion exchange-annealing treatment and subsequent phosphorylation. The resulting nanofibers can serve as an efficient electrode material for sodium storage, affording a reversible capacity of 224.7 mAh g−1at 200 mA g−1and a superior high-rate cycling capability of 108.9 mAh g−1at 2000 mA g−1after 1000 cycles. XPS and HRTEM reveal that the synthesized SP-TiO2-A/B nanofibers present heterojunction-boundary between anatase/bronze binary-phase and well-crystallized internal-structure with disordered/amorphous surface, and a high ratio of active surface was motivated through phosphorylation and Na+ion storage behavior was efficiently modulated. The surface phosphorylation engineering provides a promising strategy to develop Na-storage electrodes with superior electrochemical performance.
