Electrochemical Properties for the Lithium Ion Conductive (100‐x ) ( 0.6Li2 S · 0.4SiS2 ) · xLi4SiO4 Oxysulfide Glasses

摘要: Thermal, electrical, and electrochemical properties were investigated for the (100-x)(0.6Li 2 S0.4SiS )xLi 4 SiO oxysulfide glasses. The glass with x = 5 exhibited high electrical conductivity of about 10 -3 S cm -1 at room temperature, stability against crystallization, good chemical in contact Li metal. Cyclic voltammetry also suggested that this has a wide window more than V. On other hand, further addition up to 20 mol % lowered conductivity,
