Introduction

Inorganic solid electrolytes have been studied in two types of solids: crystal and glass [1, 2]. Glass ion conductors have several advantages: high conductivity based on so-called open structure is achieved at wide chemical compositions and single ion conduction where only targeted ions such as Li+ ions are mobile is realized. Glass ion conductors are a promising solid electrolyte for highly safe all-solid-state batteries on the basis of a free of hazards of leakage and flammability of the electrolytes [3]. In this chapter, features of glass electrolytes with Li+ ion conductivity are demonstrated and recent development of all-solid-state rechargeable lithium batteries with glass electrolytes are reported.

Conductivity of Glass Ion Conductors

A principal strategy to develop the conductivity of glass electrolytes is to increase the number and mobility of lithium ions. Figure 1shows the composition dependence of electrical conductivity at 25 °C for oxide and sulfide glasses...
