| 英文摘要 | Dual N-doped TiO2/Si/C ternary nanohybrid has been successfully prepared via a facile solvothermal method. Polyethylene glycol (PEG) is applied to disperse TiO2 and silicon precursors. After polymerization with hexamethylene diisocyanate (HDI) and calcination, N-doped TiO2 and carbon matrix are obtained. The contents of Si, TiO2 and C in N-doped TiO2/Si/C are about 10 %, 72 % and 18 % respectively. N-doped TiO2/Si/C shows an excellent electrochemical performance due to combined advantages of Si, TiO2 and C. The initial discharge/charge specific capacity of the N-doped TiO2/Si/C is 658/548 mAh g(-1) at a current of 0.1 A g(-1) with a coulombic efficiency of 83 %. A reversible capacity of 538 mAh g(-1) is achieved after 80 cycles. While at the high current of 5 A g(1), the specific capacity of the N-doped TiO2/Si/C can still reach 120 mAh g(-1). Electrochemical impedance spectroscopy measurements prove the improved electric conductivity after N-doping. |
