Synthesis of LiV3O8 by an improved citric acid assisted sol-gel method at low temperature

LiV3O8 was synthesized by the normal citric acid assisted sol-gel method and an improved citric acid assisted sol-gel method. The improved method compares with the normal method in detail by thermogravimetry (TG), FTIR, X-ray diffraction (XRD), scanning electron microscopy (SEM), charge-discharge test, cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Results show that the improved method can synthesize LiV3O8 successfully at much lower temperature than normal method.
