摘要：

In this study, ultra-thin nanobelts of Ag2V4O11/Ag were successfully synthesized. The synthesized ultrathin nanobelts of Ag2V4O11/Ag are highly crystalline and the thickness is found to be about 5 nm. A lithium battery using ultra-thin nanobelts of Ag2V4O11/Ag as the active materials of the positive electrode exhibits a high initial discharge capacity of 276 mAh g(-1), corresponding to the formation of LixAg2V4O11 (X = 6). With increased cycling, the electrode made of ultra-thin nanobelts of Ag2V4O11/Ag tends to loose electrochemical activity due to Ag+ ions in the ultra-thin nanobelts of Ag2V4O11 were reduced and new phase was formed.
