Structural and electrical studies on Zn2+ doped LiCoPO4

• Pure and zinc doped LiCoPO4 have been prepared by solid state reaction method.
• Unit cell volume has been increased due to doping of Zn2+.
• The conductivity of LiCoPO4 is found to be increased upon doping of Zn2+.
• The temperature dependent of conductivity for prepared samples obeys Arrhenius law.

Zinc doped LiCoPO4 was prepared by two step solid state reaction method. XRD studies ensure the formation of phase pure LiCoPO4 with olivine phase orthorhombic structure with pnma phase group. 2θ value of XRD peaks of LiCoPO4 is found to be shifted upon Zn2+ doping. The conductivity of pure LiCoPO4 is noticed to be increased by one order upon doping of Zn2+. The scaling behavior of Z″ indicates that the ion dynamical process are temperature independent for both pure and Zn2+ doped LiCoPO4. The temperature dependence of conductivity for both pure and Zn2+ doped sample obeys Arrhenius law of conduction.
