英文摘要	Recent studies on anatase TiO(2)have demonstrated its capability of performing as an anode material for sodium-ion batteries (SIBs) even though, due to poor conductivity, realistic applications have not yet been foreseen. In order to try to address this issue, herein, we shall introduce a cost effective and facile route based on the co-precipitation method for the synthesis of Mo-doped anatase TiO(2)nanoparticles with AlF(3)surface coating. The electrochemical measurements demonstrate that the Mo-doped anatase TiO(2)nanoparticles deliver an similar to 40% enhanced reversible capacity compared to pristine TiO2(139.8vs.100.7 mA h g(-1)at 0.1 C after 50 cycles) due to an improved electronic/ionic conductivity. Furthermore, upon AlF(3)coating, the overall system can deliver a much higher reversible capacity of 178.9 mA h g(-1)(similar to 80% increase with respect to pristine TiO2) with good cycling stability and excellent rate capabilities of up to 10 C. The experimental results indicate that the AlF(3)surface coating could indeed effectively reduce the solid electrolyte interfacial resistance, enhance the electrochemical reactivity at the surface/interface region, and lower the polarization during cycling. The improved performance achieved using a cost-effective fabrication approach makes the dually modified anatase TiO(2)a promising anode material for high-performance SIBs.
