A new material LiBiP2O7 was prepared by solid-state reaction method. The XRD analysis confirms the formation of the sample. The Raman analysis indicates the presence of characteristic bands for a (P 2O7)4- group in the sample. The electrical characterization was carried out using the impedance spectroscopy method in the frequency range of 1 KHz-5 MHz. The bulk conductivity of the material was extracted from the impedance analysis and was found to be in the order of 10-7 Ω -1 cm-1 at 473 K. The activation energy was calculated from the Arrhenius plot and was found to be 0.37 eV. The modulus peak maximum shifts to higher frequencies with an increase in temperature and the broad nature of the peaks indicates the non-debye nature of the material. The high value for the activation energy calculated from the conductance spectrum indicates that some energy has been utilized in the creation of charge carriers.
