Abstract
Stoichiometric ratios of AR grade AgI, Ag
2O, V
2O
5 and CeO
2 were melted in
a furnace and the melt was rapidly quenched to liquid nitrogen temperature to form
a glass. The glassy nature of the sample has been confirmed by powder X-ray diffraction
technique. The microstructure and microanalysis studies of the silver cerium
vanadate (SCV) have been carried out by scanning electron microscopy (SEM)
and energy dispersive analysis of X-rays (EDAX). The SEM micrograph of the
as-quenched melt showed crystalline AgI precipitate on the surface of the
solid as well as glass-in-glass phase separations. The X-ray diffractogram
of the powdered SCV sample confirmed the crystalline structure to be AgI.
Several batteries were fabricated from the sample, each battery with a 1 :
1 ratio of silver powder and glass in the anode and a 5 : 5 : 1 glass, iodine
and carbon mixture in the cathode. The batteries were discharged at 30
A,
40
A and 50
A load currents.
