Comparison of the DC and AC Conductivities of Li2O-P2O5 Glass
Lithium phosphate glass with composition of 45Li2O-55P2O5 (in mol%) was prepared by the conventional melt quenching method and the electrical properties were examined by DC conductivity and impedance spectra.It was found that the difference between DC conductivity and DCtot conductivity deduced from impedance spectra was distinct.Difference of activation energies obtaining by DC and DCtot conductivity implied that the conduction mechanism was different.The glass of 45Li2O-55P2O5 is lithium ion conductor while the oxygen ion in the glass can migrate in some conditions.
