Abstract

Oxyfluorophosphate glasses containing about 80 mol% of [LiF+Li2O] show unusually high lithium ion conductivity at elevated temperatures. A detailed investigation has been carried out on the glasses prepared by both conventional cooling and a rapid quenching technique. Chemical analysis of the glasses reveals fluorine loss during melting and it becomes difficult to make glasses with exact predetermined compositions. Electrical conductivity of the glasses, determined from complex impedance analysis increases with Li2O content. A glass with nominal composition 70 LiF∶15 Li2O∶15 Al(PO3)3 shows the highest conductivity (~ 1.3×10−3 ohm−1 cm−1 around 200° C) among all the compositions studied. An interesting feature of the impedance plot is the near perfect semicircle for bulk relaxation indicating a narrow distribution of relaxation times. This has been explained on the basis of a relatively small proportion of lithium ions which are mobile. The electrical conductivity of the glasses is found to be essentailly independent of dissolved water content. The infrared spectra of these glasses (2 to 50μm region) could not produce much useful structural information.
