摘要：
TiO2@C nanosheets have been obtained by a facile solvothermal method using titanate butoxide and hydrofluoric acid as precursors, followed by our novel carbon coating technique using oleic acid as the carbon source. The TiO2@C nanosheet anode shows a high discharge capacity of 145.8 mA h g(-1) after 50 cycles and excellent rate capability.
