The LiCoVO4 compound is synthesized by solution-based chemical method. X-ray diffraction analysis exhibits a single phase nature of the compound with cubic structure. The dielectric constant (epsilon(r)), tangent loss (tan delta) and a. c. conductivity (sigma(ac)) have been studied as a function of frequency and temperature using complex impedance spectroscopy (CIS) technique. The variation of (epsilon(r) and tan delta) with frequency at studied temperatures shows a dispersive behavior at low frequencies. Frequency dependence of sigma(ac) at different temperatures obeys Jonscher's universal power law governed by the relation: sigma(ac) = sigma(dc) + A omega(n), where n is the frequency exponent in the range of 0 <= n <= 1 and A is a constant that depends upon temperature.
