摘要
Spherical spinel Li4Ti5O12 with advanced electrochemical performances was synthesized via a facile hydrolysis-assisted process. The as-synthesized spherical Li4Ti5O12 exhibited narrow size distribution and high crystallinity, contributing to its excellent reversible capacity and utilization efficiency. At 0.1 C, its reversible capacity was close to the theoretical capacity of spinel Li4Ti5O12 (175 mA h g(-1)) and about 170 mA h g(-1) could be obtained in the voltage plateau (about 1.5 V). Even at 10 C, its reversible capacity could reach 150 mA h g(-1), which was higher than the reported pristine Li4Ti5O12. (C) 2014 Elsevier Ltd and Techna Group S.r.l. All rights reserved.
