研究了（100-x）（0.6Li2S0.4SiS2）xLi 4SiO 4硫氧化物玻璃的热学、电学和电化学性质。x = 5的玻璃在室温下具有约10 - 3Scm-1的高电导率，高的玻璃抗晶化稳定性，以及与Li金属接触的良好化学稳定性。循环伏安法还表明，这种玻璃具有超过10 V的宽的电化学窗口。另一方面，进一步添加Li 4 SiO 4至20摩尔%降低的导电性，玻璃对结晶的稳定性，和电化学稳定性的氧硫化物玻璃。
Thermal, electrical, and electrochemical properties were investigated for the (100-x)(0.6Li 2 S0.4SiS 2 )xLi 4 SiO 4 oxysulfide glasses. The glass with x = 5 exhibited high electrical conductivity of about 10 -3 S cm -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 4 SiO 4 up to 20 mol % lowered the conductivity, glass stability against crystallization, and electrochemical stability for the oxysulfide glasses.
