Abstract

The LiCo 3/5Mn 1/5Cu 1/5VO 4 ceramic has been produced by solution-based chemical route whose electrical (electrical impedance and electrical conductivity) properties are studied using complex impedance spectroscopy technique. Complex impedance results exhibit: (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. Electrical conductivity analysis indicates that electrical conduction in the material is a thermally activated process. The variation in ac conductivity with frequency at different temperatures obeys Jonscher’s power law.
