Abstract

Lithiated titanium composite oxides Li 4Ti 5O 12 were prepared from Li 2CO 3 and TiO 2. The XRD results of this composite oxides indicated that the compound had a spinel structure. The electrochemical behavior of lithiated titanium composite oxides was examined. The results showed that this material had an excellent cyclic capability and reversibility for lithium insertion, and had high specific capacity: the initial discharge capacity was 300 mAh·g -1 , and the reversible capacity was 100 mAh·g -1 . The discharge plateau (about 1.5 V) and the charge plateau (about 1.6 V) were very close on the voltage curves. X_ray diffraction results showed that the base structure of Li 4Ti 5O 12 did not change during the insertion process of lithium into the material. This material was stable for lithium insertion and extraction. The charge and the discharge results of tentative lithium_ion battery Li 4Ti 5O 12 ｜l mol·L -1 LiClO 4_PC｜LiCoO 2 indicated that Li 4Ti 5O 12 was a candidate material of negative electrode for lithium_ion batteries.
