Abstrak

Amorphous TiO2 nanoparticles are synthesized by microemulsion method using cetyltrimethylammonium bromide (CTAB) as dispersant for the first time, and then they are used to synthesize the Li4Ti5O12/C composite by a simple solid-state method. The amorphous TiO2 nanoparticles have high reaction activity with Li2CO3 to promote the synthesis of Li4Ti5O12/C composite at lower temperature and shorter time. The grain size of prepared Li4Ti5O12/C composite with different carbon additions is less than 400 nm. The Li4Ti5O12/C composite shows high specific capacity and very long cycling life. The specific capacities of the Li4Ti5O12/C composite with 5% carbon addition at 0.1, 1 and 5 C rates are 162.4, 147.4 and 114.9 mAhg-1, respectively, and its capacity retention after 600 cycles at 1 and 5 C rates is respective 99.86% and 92.95%. The synthesis method can be used for a mass production of Li4Ti5O12/C composite in industry.
