The unique ReO3 crystallographic shear structure of TiNb2O7 has enabled its application as anode material for lithium-ion batteries, in which the lattice parameter and volume change of TiNb2O7 are often negligible during lithium-ion insertion/extraction. However, several intrinsic problems of TiNb2O7, including low electronic and ionic conductivity, can restrict its application significantly. In this study, carbon-coated mesoporous TiNb2O7 microspheres are fabricated through a simple solvothermal reaction. By combining the advantages of both the amorphous carbon and mesoporous structure, TiNb2O7/C composite exhibits superior lithium storage performance, with higher rate capability (200 mAh g(-1) at 30 C) and cyclability (191 mAh g(-1) at 10 C after 500 cycles). The improved performance is due mainly to the high pseudocapacitance and low charge transfer resistance obtained from the mesoporous structure and amorphous carbon layer. The study provides a new way of constructing TiNb2O7 for ultra-fast storage devices, demonstrating great potential for application in power batteries. (C) 2020 Hydrogen Energy Publications LLC.
