On the possibility of using silver salts other than Ag2CrO4 in organic lithium cells

Several silver salts, including compounds listed in the literature and new compounds, have been examined to ascertain if their performances as cathodes for lithium cells could exceed that of Ag2CrO4. Discharges at various rates, polarization and cyclic voltammetry experiments were used to characterize their behaviour. Coulombic and X-ray analysis have enabled information to be obtained on the discharge reactions but the reductions of the anions still have uncertain features. Of the compounds examined, Ag4P2O7 is the most promising one, especially by virtue of a higher load voltage. Ag5IO6 and AgIO3, at low rates, and AgIO4, at high rates, also approach the performance of Ag2 CrO4
