Various compositions of silver-based superionic conducting [AgI – Ag2O-P2O5-Fe2O3 ] glasses were prepared by melt quenching technique. X-ray diffraction (XRD),Mossbauer effect (ME), infrared (IR), differential thermal analysis (DTA) and electrical conductivity studies were carried out to optimize the high ionic conducting composition. Solid-State primary batteries were fabricated using the 20P2O5-30AgI-40Ag2O-10Fe2O3 glass with Ag2S as anode and Ag as cathode of type; ( ( Ag2S + SE ) / solid electrolyte / Ag ). Superionic solid electrolyte glass for rechargeable battery application was performed and characterized at many conditions such as different thichnesses , different pressures , different load resistance , different temperatures , annealing times and different storage times.
