摘要：

A novel CeO2-x/TiO2 heterostructure composite is constructed with oxygen vacancies via a convenient and green hydrothermal method combined with solid phase process for high electrochemical performance sodium-ion battery. The CeO2-x/TiO2 heterostructure forms some active interfaces which can provide more sodium storage sites and accelerate sodium-ion diffusion kinetics. Thus, 10 wt%CeO2-x/TiO2 anode displays excellent electrochemical properties in Na-ion batteries including high sodium-ion diffusion coefficient (7.1303 x 10-12 cm2 s-1), extrinsic pseudocapacitance contribution (67 %) and specific discharge capacity (325.2 mAh & sdot;g- 1) at 0.1 C current rate. In addition, a superior long cycling performance over 500 cycles even at a high current density (1 C) have been presented and therefore our work is a good strategy for the application of titanium-based metal compounds in sodium-ion batteries.
