Synthesis and Characterization of M+Co V2O5 (M+ = Li+, Na+, K+)and Their Electrochemical Impedance Spectroscopic Studies

The electrical conductivity of M+CoV2O5 was investigated as a function of the nature of the transition-metal cation. A series of M+CoV2O5 (M+ = Li+, Na+ and K+) materials have been synthesized by soft hydrothermal technique at moderate pressure and temperature conditions. Observation through a Scanning Electron Microscope shows that microstructures of the resultant materials. The resultant powder X-ray diffraction confirms that, the M+CoV2O5 (M+ = Li+, Na+ and K+) material has very good crystal structure. The EDAX spectrum shows the clear identification of metal composition. The FTIR studies revealed that the presence of O-H molecules and minute structural variations of synthesized materials. Impedance measurement revealed that the materials have relatively good ionic conductance. (C) 2017 Elsevier Ltd. All rights reserved.
