Abstract
In this paper, the authors report the synthesis of Li 3VO 4 by the citrate sol–gel method and solid-state reaction method. The powder and sinter samples were characterized by DTA–TG, XRD, TEM, SEM and the AC impedance technique. Compared with the samples obtained by the conventional solid-state reaction, the experimental results show that the Li 3VO 4 samples prepared by the citrate sol–gel method, of which the diameter of the powders is about 80 nm when the molar ratio of metal ions and citric acid is 1:3, needs a lower a temperature and has a greater ionic conductivity.
