Glass exhibiting an increased ionic conductivity could be an attractive material for the construction of electrochemical solid-state devices such as ion-selective sensors, batteries, fuel cells, and electrochromic devices. In these devices the glass can function as a membrane, solid electrolyte or electrode if shows mixed electric conductivity. Amorphous nature gives glass considerable advantages comparing to polycrystalline materials.If we use chemical composition systems with a good glass-forming ability, we can add many different cations and this way "tune" glass properties. Because a large portion of glass volume is occupied by oxygen atoms, many glass properties are strongly influenced by the state of oxygen atoms, especially by the the electron density. God glass-forming ability is exhibited for example by alkali-phosphate glass.
