Solid-state batteries using silver-based glassy materials

A new, fast ion-conducting, silver seleno molybdate (SSM), glassy electrolyte has been synthesized. Solid-state primary cells of the design anode/solid electrolyte/cathode have been fabricated with the highest conducting composition of the SSM glass as the solid electrolyte. The polarization and discharge characteristics of the cells are studied with different compositions of the cathode material. The effect of adding the solid electrolyte and tetraalkylammonium iodide (alkyl = methyl, butyl) to the cathode on the cell performance is investigated. The cell parameters are evaluated and the results are compared with a cell of the type Ag/AgI/(iodine + graphite) (I + C) that is fabricated using polycrystalline AgI as the solid electrolyte.
