چکیده انگلیسی
The Li4Ti5O12/Ag composites were prepared by thermal decomposition of AgNO3 added to Li4Ti5O12 powders. The influence of the Ag contents and the mixing media on the particle size, morphology and electrochemical performance of Li4Ti5O12/Ag composites were investigated. The highest discharge capacity of the Li4Ti5O12/Ag composite reached at the 5 wt.% of Ag content. Compared with alcohol medium, distilled water as mixing medium presented the Li4Ti5O12/Ag composite with higher specific capacity and better cycling performance, leading to a reversible capacity after 50 cycles of 184.2 mAh/g with a capacity degradation of 3.31% compared to the second cycle at 2 C rate.
