A 50Li2SO4・50LiPO3 (mol%) glass was prepared by use of a traditional melt-quenching method. The structure and ion-conductivity of the glass were changed by the temperature at which the mother-melt of the glass was melted for the preparation of the glass. The Li2SO4 component was decomposed into Li2O and SO3 gas during the melting and the generated Li2O reacted with PO3- oxoacid-salt unit and produced P2O74- unit in the melt. The conductivity of the glasses was slightly increased with an increase in the temperature at which the melt was obtained for the glass- preparation. The 50Li2SO4・50LiPO3 glass obtained from the melt at 800°C showed the Li+-ion conductivity at 298 K, σ298K = 2.2 x 10-6 Scm-1. An all-solid-state battery was composed with the 50Li2SO4・50LiPO3 glass obtained from the melt at 800°C as solid electrolyte and with the cathode active materials LiNi1/3Mn1/3Co1/3O2. The all-solid-state battery showed good charge-discharge performance at 100°C.
