Electrochemical properties for the lithium ion conductive (100-x)(0.6Li{sub 2}S{center{underscore}dot}0.4SiS{sub 2}){center{underscore}dot}xLi{sub 4}SiO{sub 4} oxysulfide glasses

Thermal, electrical, and electrochemical properties were investigated for the (100-x)(0.6Li{sub 2}S{center{underscore}dot}0.4SiS{sub 2}){center{underscore}dot}xLi{sub 4}SiO{sub 4} oxysulfide glasses. The glass with x = 5 exhibited high electrical conductivity of about 10{sup {minus}3} S cm{sup {minus}1} at room temperature, high glass stability against crystallization, and good chemical stability in contact with Li metal. Cyclic voltammetry also suggested that this glass has a wide electrochemical window of more than 10 V. On the other hand, further addition of Li{sub 4}SiO{sub 4} up to 20 mol% lowered the conductivity, glass stability against crystallization, and electrochemical stability for the oxysulfide glasses.
