| Abstract: | Spinel Li4Ti5O12 coated by highly dispersed nanosized Ag particles was synthesized via a facile and effective ultrasonic-assisted method in this paper. X-ray diffraction (XRD) results indicated that Ag was not doped into the lattice of spinel Li4Ti5O12. The as-synthesized Li4Ti5O12/Ag exhibited enhanced electronic conductivity and excellent electrochemical performances. Its electronic conductivity was increased about four times compared to that of the pristine Li4Ti5O12. Even at 10 C rate, the as-synthesized Li4Ti5O12/Ag could keep 86.5 % of the reversible capacity at 1 C rate and its reversible capacity was higher than 140 mAhg?1 whereas those were 75.3 % and 118 mAhg?1 for the pristine Li4Ti5O12. |
