With excellent specific capacity, superior cycle stability, safety and strong practical, Nb
2O
5 has been considered as one of the prospective anode materials for lithium-ion batteries (LIBs). However, current study suggests that Nb
2O
5 electrode materials for LIBs still face the vital issues of low electrical conductivity and poor rate performance. Therefore, carbon-coated TT-Nb
2O
5 materials are designed and synthesized through solid state method in this work, which present high specific capacity (228 mA h g
?1 at 0.2C), satisfactory rate properties (107 mA h g
?1 at 20 C). The outstanding electrochemical property can not only give the credit to the pseudocapacitance effect of TT-Nb
2O
5, but also attribute to introduction of carbon. The homogeneous carbon-coated materials enhance the electrical conductivity, increase the electron transmission speed and alleviate particle crushing. This research not only offers a new method for preparing excellent electrode materials, but also provides a kind of excellent anode material with prospective application for LIBs.
