The highest conducting composition of the silver selenoarsanate (SSA) compound was prepared by a melt-quenching method and its glassy nature was confirmed by X-ray diffraction. Primary cells with the configuration: anode (Ag + (solid electrolyte, SE))/SE glass (SSA)/cathode ((iodide, I) + (graphite, C) + SE + (tetra-alkylammonium iodide, TAAI)) were fabricated. Their characteristics were examined in order to estimate the life time. In particular, a study was made of the open-circuit voltage (OCV), polarization and discharge behaviour of three different sets of primary batteries made up of SSA glassy compound with various cathode materials.
