Ionic transport and battery characterization studies in (30-x)Na2O --- xNaF---60B2O3---10Tl2O glasses

The results from measurements of the d.c. electrical conductivity of the Na2O---NaF---B2O3---Tl2O glass system and the transference number are reported. Electrochemical cells with the configuration Na/(30Na2O---60B2O3---10Tl2O)/(graphite + iodine + electrolyte) have been fabricated and the discharge characteristics examined. The open-circuit voltage and the short-circuit current (maximum) are 2.27 V and 2.19 mA, respectively. Several other cell parameters are reported.
