Synthesis and Characterization of Silver Vanadium Oxide as a Cathode for Lithium Ion Batteries Nguyen, Van Hiep; Gu, Hal-Bon;
β-AgVO3 nanorods have been successfully synthesized using a soft chemistry route followed by heat treatment. They were characterized by X-ray diffraction and field emission scanning electron microscopy, and their electrochemical properties were investigated using cyclic voltammetry, impedance spectra, and charge-discharge tests. The results showed that the smooth-surfaced nanorods are very uniform and well dispersed, with diameters of ~100-200 nm and lengths of the order of several macrometers. The nanorods deliver a maximum speciﬁc discharge capacity of 275 mAh g-1 at 30 mA g-1. They also demonstrated good rate capability with a discharge capacity at the 100th cycle of 51 mAh g-1.
