摘要：

We have developed the high ionic conducting glass-ceramics with the crystalline phase of Li1+x+yAlx(Ti2-yGey)P3-zSizO12 with the NASICON type structure. This type of glass-ceramics exhibits high lithium-ion conductivity of 10(-4) S cm(-1) or more at room temperature. Although this glass-ceramics reacts with Li metal gradually with the passage of time, we have improved the thermal and electrochemical properties by controlling constitution of Ti and Ge in the Li-ion conducting glass-ceramics with the NASICON type structure. Those glass-ceramics worked well as electrolyte of a lithium-ion secondary battery by the charge-discharge test using a half cell with LiFePO4 cathode at room temperature.
