| Abstract: | Silver phosphate
glasses doped with various compositions (0, 1, 5, 10 and 15 wt%) of some metal
chlorides, viz, lithium, sodium, magnesium, lead and copper are prepared by
melt quenching technique. These glasses are characterized by X-ray diffraction
analysis, FTIR spectra, transference number measurements and electrical
conductivity studies. The glasses exhibiting maximum electrical conductivity
are used as solid electrolytes for the fabrication of solid-state batteries
with the cell configurations: Ag || Ag2O – P2O5
– MCly || (C + I2) (where y = 1 when M is
Li or Na; y = 2 when M is Mg, Pb or Cu). The open circuit voltage (OCV)
and discharge characteristics of all the fabricated batteries have been
studied. The addition of metal chlorides to silver phosphate glass matrix
results in a substantial increase in the OCV. The cell with the configuration
Ag || Ag2O – P2O5 – (15%) Li Cl || (C + I2)
gives the best performance. The results have been discussed on the basis of
FTIR and electrical conductivity studies. |
