Synthesis Of Liv_3o_8 By An Improved Citric Acid Assisted Sol-gel Method At Low Temperature

摘要

LiV_3O_8 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 thermo-gravimetry (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 LiV_3O_8 successfully at much lower temperature than normal method.
