Transport mechanism in a ceramic system: LiCo3/5Fe1/5Cu1/5VO4

► Structural and electrical properties of LiCo3/5Fe1/5Cu1/5VO4 are studied. ► The field emission scanning electron micrograph indicates grains of unequal sizes. ► Electrical modulus study shows a non-Debye behavior of the material. ► The electrical conduction in the material is a thermally activated process.
