Transport properties and battery performance studies of AgI-Ag2O-Se2O-P2O5glass

Various compositions of silver-based quaternary superionic conducting (SIC) [AgI-Ag2O-(SeO2 + P2O5)(SSP)] glasses were prepared by melt quenching tech nique. The X-ray diffraction (XRD) and conductivity studies were carried ou t to identify the amorphous nature and to select high ionic conducting comp osition of the SSP system for the fabrication of batteries. Solid-state pri mary batteries were fabricated using the 66.67%AgI-23.07%Ag2O-10.26%(0.3SeO (2) + 0.7P(2)O(5)) (66SSP37) glass with different cathode materials [I:C, ( I + C):SE and {(I + C)+ SE}:TAAI, where I is Iodine, C is graphite, SE is s olid electrolyte (SSP,glass) and TAAI is tetraalkyl (methyl and butyl) ammo niumiodide]. The open circuit voltage (OCV), polarization and discharge cha racteristics were measured to estimate the lifetime of the batteries made u p of SSP glass. (C) 2000 Elsevier Science S.A.
