Nitrogen-doped TiO2 is in situ synthesized by plasma enhanced atomic layer deposition on carbon nanotubes (N-TiO2/CNTs). The prepared N-TiO2/CNT nanocomposites are employed as anode materials for sodium ion batteries. The specific capacity of an N-TiO2/CNT electrode is 1.45 times higher than that of a TiO2/CNT electrode at a current density of 50 mA g-1 after 200 cycles. It is demonstrated that N-TiO2/CNTs are more effective in an electrochemical Na cell due to the enhanced kinetics which results from the nitrogen-doping and the amorphous feature.
