Abstract
We demonstrate a unique synthetic route for oxygen-deficient mesoporous TiOx by a redox-transmetalation process by using Zn metal as the reducing agent. The as-obtained materials have significantly enhanced electronic conductivity; 20times higher than that of as-synthesized TiO2 material. Moreover, electrochemical impedance spectroscopy (EIS) and galvanostatic intermittent titration technique (GITT) measurements are performed to validate the low charge carrier resistance of the oxygen-deficient TiOx. The resulting oxygen-deficient TiOx battery anode exhibits a high reversible capacity (∼180mAhg-1 at a discharge/charge rate of 1C/1C after 400cycles) and an excellent rate capability (∼90mAhg-1 even at a rate of 10C). Also, the full cell, which is coupled with a LiCoO2 cathode material, exhibits an outstanding rate capability (>75mAhg-1 at a rate of 3.0C) and maintains a reversible capacity of over 100mAhg-1 at a discharge/charge of 1C/1C for 300cycles.
