| Abstract: | The precursor（Li1.81H0.19） Ti2O 5 ·0. 262 5TiO2 were prepared by template method with titanium tetrachloride and lithium hydroxide as raw materials,and then to obtain lithium titanate（Li4Ti5O12） by calcination. The optimum preparation conditions were that when molar ratio was 4∶ 1 of template： Ti, and calcined at 700 ℃ for 1 h. The particle size was 10 ~ 100 nm by TEM,the fitting particle size was 5 ~ 30 nm by XRD,and the specific surface area was 100 ~ 600 m2/g. |
