Polyaniline (PANI) wrapped Ti2Nb10O29 (TNO) micro-spherical composites were successfully synthesized via a solvothermal approach combined with a facial post in-situ polymerization method. Effects of different amounts of the PANI coatings on the composite microspheres’ electrochemical properties were studied in detail. Results showed that the electrochemical performance of TNO@PANI anodes with 5 wt% PANI is the optimum among all the samples, giving capacity values as high as 272 mAh/g (1 C) and 190.1 mAh/g (20 C), respectively. Moreover, the electrochemical impedance measurements exhibited that 5 wt% TNO@PANI composite electrode material possess a weaker charge transfer resistance. This indicates that an appropriate amount of polyaniline coating can effectively improve the electronic conductivity of TNO microspheres and subsequently the electrochemical properties. In this work, we have demonstrated that 3D TNO@PANI composite microspheres not only deliver a higher initial Columbic efficiency but also can serve as next-generation lithium-ion battery electrode material with enhanced rate performance.
