Electrical investigation of the compound: LiFe2/5Ni3/10Co3/10VO4

The LiFe2/5Ni3/10Co3/10VO4 ceramics has been produced by solution-based chemical route. Orthorhombic unit cell structure of the compound is selected by X-ray diffraction study. Complex impedance spectroscopy (CIS) technique has been used to study the electrical properties. Complex impedance analysis shows: (i) grain interior, grain boundary and electrode–material interface contributions to electrical response and (ii) the presence of temperature dependent electrical relaxation phenomena in the material. Temperature dependence of dc and ac conductivity indicates that electrical conduction in the material is a thermally activated process. Frequency dependence of σac at different temperatures obeys Jonscher's universal power law governed by the relation: σac = σdc + Aωn.
